How can I stop hating my brother?

He made my childhood a misery and I haven't seen him in 10 years. It's his 65th birthday this week and I was surfing and found a picture of him on Facebook smiling all over his face at his daughter's marriage and a great surge of anger went through me. I just hate him for what he did to me and my mum. After my dad died, he became a violent bully. He used to knock me and my mum around, he made my mum so unhappy, he used to criticise and laugh at me, he wanted me to leave school early, he resented everything I did. He has never in the whole of his life complimented me on anything in my life. His life looks to me like a mess, his second marriage has lasted a while (the first one ended when he beat her up and then had an affair and left), but the three stepsons left home as soon as they could. The daughter who he dotes on left school at 16 and has now married age 20. I hate his wife too, she's loud and insensitive. He made some moves to see us last year and I blocked them. I'd like him to admit what a sh*t he is, but of course even if he could see it (which I doubt) he wouldn't. I so much wish I could see him suffer for how he was and I really hope he dies soon. So, should I send the birthday card to someone I hate so much?
