Yes, you were making excuses for bad behavior. He was mentally ill, he had a drug problem, he was homeless.........yes, these are all sad conditions, but none of them excuse his multitude of crimes against a number of people throughout his life. EVERYONE has problems. Some people address them, and others take the easy path. Some are better equipped to deal with problems than others, but that doesn't mean it can't be done.
At no point did I ever "mock" the man who died on the subway, nor do I take pleasure in anyone's death, as you alleged. I have no idea where you got that idea. I simply pointed out the huge difference between the two people who were responsible for the victims' deaths.
I will never excuse people who put others in danger, regardless of their sob story or background. There is never an excuse.
