How do I stop having the desire to kill?

I thought it was going away one day but now every time I get angry I just feel hate , I feel like I should kill important people, I feel like I should dictate how things should be , I feel like I should put down anyone that gets in my way

And I know this isn't good at all , I feel guilty for feeling like this but I can't control my own thoughs, I just want to feel normal , what can I do ?
