Why?
First off, I have say I love this movie! Everything about it. Save, I think, the death of Adam Beach's character. And speaking of, WHY did T.J. kill John? WHY?
shareJT was just your stock macho redneck and John threatened his sense of manliness, 'white is right' etc...Think about it, John pissed him off by getting in the way with Angela, punching JT out, and then to top it off he witnessed them assaulting her and could have gone to the authorities...
Life is like a jar of jalapenos: what you do today, might burn your ass tomorrow!
