You have 5 hours to give a good reason to be a moral person.
Hard mode: don't use circular logic, e.g. "you should be moral because it makes you a good person, bro"

prison

Because it feels best in the long run.

>all immoral people go to prison

People will like you more, which gives you advantages.

That's an argument for pretending to be moral, not being moral.

I will hit you in your stupid fucking face otherwise.

If you aren't a born psychopath or a sociopath because of your environemnt you can't help but being, at least in a weakened form, moral person.

I understand how psychopaths think and can rationalize their behaviour but I could never act like them.

If someome gave you money to rape and maim a little girl, you maybe think that's not a bad idea but the moment you see a little girl cry, you would stop doing it because your mirror neurons make you feel the pain.

So moral thinking and acting is innate in humans and many animals.

The only thing that can change is what you consider to be morally. Is there an objective morally right or wrong?

And you also want to be a moral person because it is best for everyone, yourself included. If your country has developped certain moral views it is because it has worked in their favour. I dont want people to steal from me and I dont steal from other people. And with every moral person it is easier to detect the psychopaths and exclude them.

if you don't have natural morality, then there's no point in faking it. If you have to ask this question, just accept that you are not a moral person.
