i'm just not 100% sure where the morals/ethics line is supposed to go.

I'm not amoral it just seems like people arbitrarily draw lines and they seem so certain.

You have to draw your own lines, ones that are important to you. You shouldn't let others tell you where does lines are.

As Martin Luther King Jr said:

Ultimately you must do right because it’s right to do right. . . . You must do it because it has gripped you so much that you are willing to die for it if necessary. And I say to you this morning, that if you have never found something so dear and so precious to you that you will die for it, then you aren’t fit to live.
