But I do see a difference between someone who kills someone for money (for drugs) and someone who kills for pleasure. I believe that the hate crime rules were enacted to attempt to punish (harsher) those who kill for pleasure.
Nope. Hate crime laws were passed to punish whites for killing blacks more harshly than blacks killing whites. Some of that may have been influenced by the (perhaps perceived) inequality of white vs. black sentencing, but whatever else may have prompted it, punishing whites harder is the reason for it.
I have yet to hear of one black-on-white hate crime being prosecuted.
I'd be happy to be proven wrong.
