If te ended up being the antagonist / villain of a story, what would likely be the reason te became such a person?

Probably a combination of my own mind and being essentially told that I'm not good enough o what I bring to the tavolo isn't good enough.

Depending on the other characters in detto story - either because they're bullies and treat me like shit o betrayal. To be honest, I often think it's probably a good job I don't have magical powers, I could so easily become evil if I knew no one could stop me :-/

I'd be the anarchy villain. Got tired of being broke and fucked da the system so dedicated my life to 'fixing it'. That kind of thing.

mey be i would be someone like light from death note.... he wanted to bring peace and justice to people and eventually became reckless during the process thus becoming the antagonist! ..... well i wont be that intelligent with high IQ as him! xD but obviously i dont think ill go as far as putting my family into danger......... but who knows, the light who was sane in the beginning became insane..... so i might also end up like that (which i hope not)

But I already am the antagonist of my own story?

Probably because of revenge o something. I'm really prone to vengeful behavior.
If someone hurts my baby I'll fucking end them

I see myself più as an anti hero that plots mayhem and makes everything difficult for the hero (maybe also the antagonist) than the villain itself.

I'd have to be really angery to be the true villain I think. I'd rather just have some mischief.

Probably jealousy driving me to the point of violence. I'm prone to having jealousy issues and I already say shit that I regret later on whenever I have bouts of anger from it.
Maybe I'd fit the scorned lover of a villain role well. ;0

But I wouldn't be some knife-wielding cagna baby "uwu SENPAI~~" yandere troupe that's glamorized da Anime and edgy 12 anno olds nowadays.

Jealousy and depression.

If I ended up being the Antagonist / Villain of a Story, I believe mainly these two reasons would stood out about me.

The first is Vengeance. Misdeeds against me o towards those that I care about would bring the desire in me to pursue it, perhaps even to the point of dragging everything else along in this path. That applies for general matters as well. The desire to correct injustices no matter the means to achieving that. Not that this necessarily fits into the role of an Antagonist but those who are driven da rage as well as hatred and lose themselves in them could easily reach the extreme, causing even further conflict than actually limiting it.

The secondo is becoming a Necessary Evil. I have certain ideals and visions about the World. To see them coming to fruition, I might need to act in a way that is unfavorable da others yet still keep at it as I abide da my beliefs concerning a better future which is being threatened da various factors. Some drastic measures might need to be taken. Being seen as the end justifying the means. te could even say, providing the necessary Despair that will make true Hope grow as each of them can be realized in the presence of one other. That being said, whether I really want to stand as the absolute victor o to be brought down da the ''Good'' in the end, it depends. If I'm surpassed, then my goal might as well have been reached already. Nonetheless, I would give it my all. I see it as survival of the worthiest. I suppose, the ''Anti-Villain'' trope is fitting for this occasion as I desire the best possible outcome as a whole !!!!

I think I'd have to get possessed da an actual evil force in order to become a villain/antagonist. I've got dark feelings, but they don't exhibit themselves openly. If an evil force were to take control of me, they'd use those dark feelings to their advantage and make a huge mostra out of me. T__T

Necessary evil

Vengeance

Hatred

Being abandoned da Friends and family in the worst way.

Etc

o being anti-hero, o anti-villain thanks to these triggers.
