Let me also add that it clearly states this in the Bible. Jesus ask one of his disciples "what do they call me?" He replied "You are the Son of GOD". Jesus then ask again "who do you think I am?" The disciple answered "You ARE the Son of GOD". There it is folks, a conviction from the heart of what he saw and witnessed. The teachings of Jesus goes far and beyond what a child may think. Many "christians" have it wrong on so many levels, so let me explain. When you do a deed, be it a good deed or an ill will deed...the reward for the deed is termed "good" when that person believes that it was. Goodness is the reward. His feeling of "goodness" or self gratification IS the reward. When an ill-will deed has been committed, the person who did that deed does not believe that what he/she had done is wrong, there is no conviction from that person yet until others dissect the motive for the deed. His deed is confirmed as an "ill-will" presented by the motive. He still gets his reward from his ill-will deed because of his gratification but it quickly changes when others believed that it was nothing but EVIL.
How to resolve if others think your deed was "evil". In this scenario, you are given two chances to redeem yourself. First, you have consistently bring FAVOR to the person or people you have brought that deed upon. If you can not do that, then the second chance is for you to ask for their forgiveness. You do whatever it takes to get that forgiveness. These are the two chances that you will only get. The game of Baseball is a game of 3rd strike and you are out BUTTTTTT, you are given 2 chances.
Killing is the worst of all ill-willed deed and it is the most evil. Not because the deed will haunt that person forever but because you will no longer be given the chance to ask forgiveness or repentance. Killing other people so your life could be lived will make you the DEVIL. And that was what Cain did to Able. Yes, Cain spelled "lived" backwards and got "devil" so that he could "live" being "evil".
