Hmm... This
is an interesting question. I agree with Lightkeeper that you would have done the right thing by saving the baby. The baby, saved by the same power, could have just as easily grown up to be Ghandi, or Martin Luther King, Jr. Since you had no way of knowing what would ultimately be done, the only action that you would be responsible, which would be the saving of a life.
The question of whether intentions can be both bad and good is another interesting one. In most cases where I could see an intention being both, I would see the person as consciously thinking they were doing right, while unconciously (or subconciously) doing the same thing, but with a wrong intent. I apologize for my tendancy to use "Lord of the Rings" analogies, but this is the only one that jumps to mind...
Boromir (the bearded guy with the horn and shield, for anyone who only saw the commercials) wanted to use the Ring, from his
concious thoughts, as a force of good. He thought it would help him defend his country and to bring peace to mankind.
Unconciously, (though it wasn't his own soul trying to subvert him, but anothers'), he wanted the thing because of its' power and because, through it, he could control others. He was ultimately tempted by the Ring (can't you just imagine it whistling "Hey, there, cutie!"
) and tried to take it from someone. Although he was able to ultimately redeem himself through his bravery, he didn't recognize the unconcious voice until it was too late. Actually, though, all of this was what partially led to peace being returned to the land. So, as in Lightkeepers' example, there was
some ultimate good that came out of it. (I realize that this is fiction, whereas the other is fact, but it was the only example about duality of intent that jumped to mind.)
Can anyone think of any cases where a person conciously wanted to do wrong, but unconciously wanted (or wound up doing) right?
