Whatever you do they are people who think that you're an antagonist in their stories. Why is like that?
Every person who has different minds creates conflicts. We have different beliefs and values. Sometimes even we have similar goals but we still have different agendas for our goals. We have different ways how we get our goals in life. We have different principles that we can sees as how we step for our own path and how we deal for our situation.
Example is you agree for killing criminals but others see it wrong to kill criminals because they see it as human. We have different ideas to have our peace. There is Aristotle saying.
"We make war to may live in peace"- Aristotle
We fight for our ideas because we think this is right for our society. Who opposes us can delay our success. So we do everything to stop for what they believe.
Even if we have the same values we can still do conflicts because of personal things. Maybe you're competitive and you don't want to lose. So you do everything to put down someone who is blocking your way. You think they're the antagonist of your story.
Even if you're not competitive, there are people who are insecure about you. You don't need to be perfect to why they're insecure to you. Because they're things that you have that they don't have it.
They are people who are using you as an instrument or as a stress reliever. Whatever you do there are people who make drama about your life and make you an Antagonist.
