Should I turn into a bully again?
Probably not. Why do you want to become a bully again?
Because everyone else who bullied me is now dead.
Is there a lot of solid, lasting payoff in being a bully for you? Think about how much better consequences you would experience if you were a nice person. And consider how hard it was to quit being a bully in the first place.
Bullying is great, I'm will start feeling so much better when I start to bully others.
You might feel better but that people that you bully will not feel better that you are doing that to them. Plus now there are more laws against bullying then when you were younger.
