I am full of anger and hate

I was born and raised poor and i couldn't have many things i wished in my childhood and teenage time. I truly believed i deserve an amazing life. i am smart, well educated, good looking and others tell me these things too. But my memories are nothing but repetitive boring days and years without anything worth to talk about. i see those as a gap in my life. but more important thing is i remember every single insult i heard and every person's face who said them. i am abnormally sensitive to them and i have stronge desire to find every person i hate and kill it so my fire inside chills down. yes, i feel the thirst for murder just for a single insult!
I‏ am studying law right now and going to become a court judge few years later. so i will reach a level of authority that i would/should view majority of people lower than myself in terms of power and probably some other aspects too. i am also planning to get the most out of the money i earn by buying stocks or even starting business. but sometimes i view my position as a judge in a different way. that it will be a good tool for me to get my revenge and finish some undone jobs i'v been waiting for all of these years. i just kill them and it doesn't even matter if i get caught, i simply say ''it was self defense''. or do this via the ''legal way''. mix up my own made documents and fake proofs and turn them into biggest criminals and hang them at the end. what do you think? what should i do to my anger and hate?
