Hey Chilled,
I used to have those kinds of thoughts when I was drinking. Haven't had them for a while now. Do you feel that they are subsiding when you are sober? I truly think the alcohol "fuelled" those thoughts into irrational levels.
Hate also comes from the past. Past wrongdoings, past disagreements. I find looking forward lets me leave it all behind. It's hard to hate the future if you're sober.
