Is it normal if the thought of being bad gives me a thrill

Negative experience should never be an excuse to be a fuck up.
I will tell you a story.
I had a friend in highschool. She had a lot of family problems. Her mother got her hooked on crack at an early age and her family was abusive.
As an adult I remained friends with her. Years passed and she had eventually gotten off drugs and had kids.
She split with the babies daddy who was a lazy pill popper who stole from everybody.
A time came where she had nowhere to go and was homeless with a newborn and a young daughter.
I took her and her kids into my home and provided them food and gave them my room never asking for rent.
I told her that babies daddy was not allowed over because I knew he was a thief.
As time passed I started noticing stuff missing. My videogames, my guitar petals and my tools.
Questioning her she admitted to letting him over while I was gone.
I called the police and asked them to check the pawn shop and sure enough babies daddy was stupid enough to pawn my stuff in his own name,
I pressed charges on the dad and expected things were done. I was wrong.
Soon after I caught her stealing. She confessed to stealing "because babies daddy was manipulating her to do it for him."
I had no choice but to kick her out. I did care about her kids but I cannot live with a thief.
I never quite understood what her motive was. I don't think the ex was sharing much pawn money with her and I know he was pawning it. She had it really good living with me, perhaps better than ever. Afterwards she tried staying with other people, who she did the same things with and was kicked out by them as well.
As of now she has lost custody, which seems for the best, and I was told babies dad molested the daughter, although I am uncertain if that is true. She is back on drugs and lives with tweakers.
Anyway you may be wondering how this story relates.
She often blames her shitty behavior on how she was treated.
That's just bullshit, because she acted that way towards the ones who actually try to help.
If you want revenge, fine, but don't ever use someone elses bad as an excuse to take it out on somebody who doesn't deserve that.

I thought you meant "bad", as in, living on the edge. Sometimes, I think about having a motorcycle or a sport car and driving very fast down a deserted highway.

It's Normal to get tired of an image and to want to change it. But, be careful how you change it. Don't do anything that you'll later regret or will cause harm to others.

Why don't you take up a sport? Take up boxing or marital arts. It will change how people view you and it will give you a safe outlet for your aggression.

I actually went through something similar. I got over it step-by-step through exploring my interest in BDSM. ;)

Learn karate. It will fix your mind.

No
also you shouldnt take out your anger on others. I find much of the time people go and do stuff they tend to hurt innocent people.

Take serial killers for example lets say a guy us murdering woman ones that resemble his mother in looks... thoes woman offten are good people living their lives.

You should seek help if you are having dark thoughts
