They would also depart. Sin (and a moral action) has all of these components in my view and they are Biblical:
1) The subjective intention of the person who acts. This can be good or evil. Having an evil intention is condemned by the Lord Jesus when He says "do not give your alms to be praised by men," and in many other places. It is the aim you have in your mind when trying to do a thing.
2) The circumstances of the act including the consequences. The "when" or "where" and effects of the act, etc. An act can have some bad consequences but always the good consequences that are reasonably foreseen must outweigh the bad consequences, it is mentioned in Scripture where it says "love does no harm." Now Christ is love and His very coming into the world had bad consequences (the murder of the Holy Innocents in an attempt to kill Him by King Herod for instance), but the good overwhelmingly outweighed the negative consequences according to Christians (the recapitulation of the world, deification of the Elect, etc, all of which goods will be infinite), so the principle is seen. This is also mentioned elsewhere.
3) The most important part: the object of your act. The reason this is the most important is it does not change and is always strictly good or bad, as can be seen with the above two things there is a binary nature to morality in Christian ethics (according to me). Bad moral objects include but are not limited to: indiscriminate destruction of cities in war, adultery, murder, lying, usury, deicide, blasphemy, and so on. Good moral objects include but are not limited to: praising God, almsgiving, burying the dead, defense of the innocent in war, loaning money without usury, freeing slaves, building beautiful things for the public, supporting your parents in their old age, and so on. A bad moral object can never be justified, a good one in itself is always justified but...
For an act to be good all three of these has to be good. If even one of them is bad (bad intention, more bad consequences than good, or bad moral object) then the action chosen is immoral.
These acts also differ in gravity, maliciously stealing $5000 in a family dispute and committing a genocide of millions to me self-evidently differ in gravity, and also God has this opinion for the Lord Jesus spoke of those who had a "greater sin."
There is yet another component (actually two) God cares for and that is what has been repeatedly said throughout: (a) knowing (b) choice.
If a person for some God-known reason genuinely and through no fault of their own does not know that serial adultery is wrong then a severe guilt will not be imputed to them and they will not go to Hell for that in my view. If a person for instance in the heat of a moment does not deliberate (b) and chooses wrongly, which they in hindsight see is wrong then the same things. If they are both saved this will merit a purification (purgatory) but not punishment (Hell).
This last thing (who knows and who chooses what) is a subjective thing, we can only in my view look at outward acts and say "this is a disorder" or "this is a good" but we do not know the state of someone's soul or what their Judgment will be, for as Scripture says "man looks at the outward appearance but God looks at the heart." This is one of the main reasons it is a sin to say "this or that person is going to Hell," for you do not know the state of their soul or what their Judgment will be, it could be that guilt is not imputed due to their ignorance or deficiencies and so they enter the Kingdom before you.
So yes in my view God cares about intention, subjective knowledge, and the ability to choose of person to choose, along with many other factors that He will consider in His Judgment. A story commonly cited about this is the drunken monk.
As for God hurting those who disagree with Him I would disagree with that. I assume you are talking of Eternal Punishment in Hell. As can be seen from the above I laid out in my view I don't actually think it works just like that. The only sin that can damn a person is this: someone freely chooses something they know to be gravely evil and they hold on to it even until death. Note the "they know to be gravely evil," it requires them to co-judge themselves with God (this is what conscience is to me by the way, co-knowledge of good and evil with God in the depths of the soul). Those who go to Hell are self-condemned, they acted evilly in full knowledge with deliberation and they knew it was evil. Why would anyone do this? As is said often in theology "sin is against reason." The person by condemning themselves by doing what they know to be gravely evil and holding on to it without repenting is participating in God's Judgment of them.
But as for participation in this Judgment by believers (who themselves go through a Judgment), we do imitate God in this and will participate in Christ's Judgment of the Universe. He (the Lord Jesus) says "the Father has given all Judgment to me," but the Church is Christ's Body so the Psalms teach in my view:
"Thou art my Son, to-day have I begotten thee. Ask of me, and I will give thee the heathen for thine inheritance, and the ends of the earth for thy possession. Thou shalt rule them with a rod of iron; thou shalt dash them in pieces as a potter's vessel." (This is said by the Father to Christ Jesus His Son)
"The saints shall rejoice in glory; and shall exult on their beds. The high praises of God shall be in their throat, and two-edged swords in their hands; to execute vengeance on the nations, and punishments among the peoples; to bind their kings with fetters, and their nobles with manacles of iron; to execute on them the judgment written: this honour have all his saints." (This is said of the Church)
So we do imitate in that way, although the time isn't yet.
