Who do 你 do things for?

Myself. The people I love. The rest of the world.

If 你 ask me, people should do good things not out of fear for their god(s) 或者 the afterlife but for belief in morality and a desire to do good.

What are the "things" and the "it" here?

My moral imperative comes from my interaction with others and the environment around me. I am accountable to those relationships.

Mostly for myself.
Sometimes, I do things for my family, my boyfriend, my imaginary friends...stuff. My Gods don't expect me to do anything for them *shrugs*. They're Gods because they can do things for themselves and everyone else.

Sorry, your 问题 is quite unclear. Like in those shows where 你 see people asking the main character what they're fighting for?
I suppose my answer would be myself. I don't really care. I mean, life is going to end pretty soon, the world is going to keep on spinning, I think we should enjoy it while we're able to. If you're able to.

Why? Lots of reason's...none of them are outta fear though. If I did something outta fear, that would mean I wouldn't be genuinely doing it for the right reason.

Now onto this real answer:

I do things not only for myself, but also for God, Jesus, my son and everyone else I love.
