Ok, to reply to Engine's post: the usage of the TZ example was to show the other side of the coin to those who say "Hell yeah!" If it's so acceptable to you (and here I'm not talking to Engine but to those who said yes) that you kill someone for money, someone you probably don't know and have no idea if they deserve to die (if anyone does), is it then equally acceptable for someone to be approached with the same offer to kill you? Would you then think of it differently and wonder why someone would kill someone they don't know, have no beef with and that has done nothing to merit such treatment?
Would you truly want someone being handed your photo and saying "don't know who he/she is but if you're paying me 50 mill then he/she is dead"?
I think it puts a different slant on things, and shows a different side to the offer, particularly for those who would accept it.
As for why we condone/don't condone murder, well, that would take more than one post, wouldn't it, and would be a whole other day's work...
