No, I get that. You try to offset one thing with another. If Dave Matthews kills a child yet pays to have another child flown to a place where he can get a life-saving transplant, does that mean he's "even"?
Some might say just don't pollute the enviornment with your tour bus and generators,etc. I guess his Earth Mother doesn't beat out tour dates in Chigago and Tulsa...
Now this is a question that is in the spirit of the article. IMHO it really depends on the circumstances in which the child was killed. If it was accidental, than Matthews actions would be a kind of penance. In God's eyes my understanding is that he would be forgiven. The OJ Simpson Jury would also surely set him free.
Of course, the point is moot given Matthews time-travelling powers. He could simply go back to a point before he killed the child and alter events.
