Oh get a backbone already. If my dad was killed by say, a group of Jews (not to be discriminatory, but it's a completely random example), I'd have blood-stained Stars of David and yamachas (no idea how to spell that) adorning my walls too. Boba could perhaps be described as a psycho-path anyway. He slaughters an Imperial Garrison to get at one man, laughs retardedly (I hate that kid actor) when his dad's trying to kill a Jedi, and had to live for years with a complete idiot of a father (I think the high-point of his life was seeing his stupid father get decapitated, I was so relieved). I wouldn't put Jedi heads past him.
Besides, I intend to keep pictures of my kills on my wall too (though heads would be nice, start to smell after awhile though), and would you call me a psychopath?
.....ok, bad example.
