No. In theory, by God telling mankind that what they do in this temporal life will be judged may in effect curb the wrongdoing as per the Islamic/Noahide law states will in fact affect their judgment. Because we cannot comprehend incorporeal judgment or things that are spiritual with our senses it is best left to describe what the next life may entail. If I told you if you walk through door #3 that is located on the right tomorrow (mind you properly labeled) you'll most likely avoid it. Now, if I got you intentionally drunk and the same rule applies you may not abide by what I said regarding walking through that door.
Now grant it you're intoxicated so a little bit of leeway may be in order by the point is on a spectrum, people may be cognizant to rules because there is an authoritative figure watching or because they believe the rules to be true because they believe there is a real punishment behind the actions, and if that is true these people are very few. If God was corporeal and physical real and at the sight of transgression would scold someone, more than likely people would avoid doing things against God's command, but considering we do not physically see God and although some may believe he exist and believe in his laws we may continue to transgress not because we want to, but because we do not physically see the authoritative figure.
I'm not saying people are incapable of being obedient absent of physical descriptions of painful judgment, what I'm saying is that the idea of potentially being judged and condemned mentally would help curb transgression.
Sure, in some cases it helps if one believes there is a consequence.
BUT there is a Danger in to this belief. If a Person believes in Day of Resurrection, and in Oneness of God, He also does His prayers, and Fast, He thinks based on Quran he is just fine, and he will be admitted to Heaven. This is dangerous. Such people may kill other people (specially non-Muslims, or unbelievers,), lie to others, and do many wrongdoings, and still feel they will be admitted to Heaven, since the Quran says, if you believe in Resurrection and oneness of God, you are basically a believer, and you are called a Muslim, and you will be favoured. Aren't there such people?
I think if we go with the Quran, it seems to me, the reason Quran emphasizes in Day of Resurrection is in this verse:
“As for those who believe not in the verses of God, or that they shall ever meet Him, these of My mercy shall despair, and these doth a grievous chastisement await.” 29:23
So, the important thing is to believe in Meeting God. But God is invisible. How are we supposed to believe in meeting Him, when He told Moses you cannot see Me. So far He always sent Messengers. If it was possible to meet Him, why He didn't come before Himself?
