I think i may understand what it is with Darth Vader

He basically goes to hell in a sense, and those who are against him the most and stand in opposition to Vader might be Christians or something like that though that doesn't completely make sense either

Just like the breathing apparatus thing his breathing what is the cause or explanation from that? I can't see Christians doing that.

It's just that what I found that might have necessarily been a hint towards the predicament of being Darth Vadered might have been Christianity
