Film really about being true to yourself

WARNING POSSIBLE SPOILERS!!!!
SEE THE FILM FIRST!!!

Which is worse? A person who is a killer and does not stop herself or make excuses or a killer who tries to do "right" because she is afraid and tries to make excuses for her own "bad" behavior whenever she acts from her heart.

I think there is a reason most religions teach to be true to yourself and act from your heart. People like Eunice do a limited amount of damage to other people because they know who they are and want and will be stopped while people like Miriam are more likely to get away with whatever damage they do and will affect many more people and will also be more likely to reproduce and pass on her sociopathic genes. With Eunice you always know where you stand while Miriam is alot harder to deal with because she always tries to hide who she really is.

The fact that Eunice tries to get God to notice her shows how much society can mess people up. Of course God knows about Eunice God is all there is. God is the source of everything true. Miriam is the one who is further from God. Miriam is the truly dangerous one.

The most chilling moment for me was when Miriam was talking to the camera and said that everyone would steal and kill and "pull the emergency alarm on the train" if they weren't so afraid. Miriam is just like Eunice just more scared. Miriam does not think she is bad even though her true self is exactly like Eunice.

So who is more dangerous? The sociopath who acts without fear and knows she does wrong or the sociopath who is too afraid to be herself and therefore fools herself into thinking she is not doing wrong?
