Depends on what kind of trolling you do. For example I do trolling sometimes on gaming, like exposing the cheaters, killing the campers (they troll too) when they don't expect it, dominate a player that thinks he is the best, but without a bad purpose. The enemy players get angry from it, but it's all part of gaming, sometimes you win sometimes you lose, you got to accept it. Being called a troll just because you got skill is wrong, that's not the reason.

I have recently did grief/troll to one of my friends by exposing him that he lost a 1vs1 match against me. I did that through posting a story in instagram and that made him very angry, because I tagged his personal account on it so that's another reason. I did a wrong thing, we didn't even talk to each other because of this. Then I realized I have hurt his feelings with that thing, which was not okay. I apologized after few days when I realized that the thing I did was very childish from me and I promised I would never do this thing ever again.

Nowadays we are sort of trolling duo, but we just annoy the other players and then we tell them it's a joke. Trolling with no bad reasons should be considered okay, should it?

Hey, Vortex. I don't think you are a bad person because you know what you are doing is not right and that it is probably hurting you more than anyone else. We all have a dark side so you are not alone in doing things that you know are wrong and that may hurt others as well as yourself. You are only human!
The fact that you recognise this is good, you can move from this if you make the effort and follow what you know is right.
Have you thought about channeling those feelings into something else? art, music? acting? sport?
If you look at it like getting rid of a bad habit, such as smoking or biting you nails it may be easier to think of something you can do instead?
You can only try. We are always here for you if you need a boost!! :))
