I so not would. What if it was your wife? Sorry to say; but somebody like that deserves that kind of things. Never cheat
I once drove thru a red light, is that a sin too? Don't know of any 'bad' things i did. Mostly just laugh at lower school where my best buddy kicked somebody's teeth out. Why? Cause it was fun and we didn't like the kid.
I had some weird friends now i think back about it, like a other friend in middle school, who kicked (together with a other friend of mine) 3 kids with their bike, into the trench next to the bicycle path. Next day all 4 of us (4th one and me just cycled on) had to report to the teacher. /sigh 'Write down on this paper what happened.'
Is hating somebody / not being able to forgive somebody a sin too? If they are your friend, that is.
