Hatefullness

I need some help and prayer with my hateful side... it's gotten out a few times on here, like when I said that killing Euronymous was the only good thing Varg Vikernes did, or when I said I'm looking forward to Kim-Jong Un showing up on the "high profile person died recently" thread. I only ever get like this for righteous anger, but there's a difference between anger and hatefulness. I know God still desires salvation for everyone.
