How can anyone be okay with Hell ?

[Watson]

So if it was socially acceptable to murder babies, that'd be okay? Or would you strongly disagree with that idea based on the obviousness of its being morally wrong.?

No it would not be ok. Anything negative done on another is considered wrong.

That's all well and dandy, I agree that murdering babies is wrong, but...

Morality is very much subjective

This doesn't match up with your above statements. There may be those who believe murdering babies is a perfectly moral and just thing to do. There may be those who believe anything negative done on another is also perfectly moral and just. So if morality is subjective, then under the right societal circumstances, murdering babies could be a completely legal thing to do.

Would you still think it was immoral?

but we do tend to have a common ethical standard. No killing, raping, stealing, ect ect.

And I ask you where we get that common ethical standard.
