Niall and his consequential decesion...
..do you think he would have acted differently if Alby was not in the courtroom that day?
Because, and this is just my personal take, feel very strongly that his main drive in that moment was to prevent himself of being exposed as a homosexuall, so basically self-preservation/selfish.
I mean, this fear never left him all his life and ruined great aspects of it. (Although now he blames Ruben for the 'fear' in his life. I think it is just a replacement for his actual fear of..)
So maybe, what is really eating him up and makes him filled to the brink with guilt (whether he acknowledges it or not), is this double shame, of not being there for his familiy (absolute emotional pressure, not a responsable parent in sight) and especially not for the one person he 'adores/is dependent on. Codependent, trauma-bonded, whatever you will.
I think this "right or wrong" thing is a too easy take, the situation is far more fumbled and complex, as to just reduce it down to morals. Nothing black and white there.
What is your take?
Edit: corrected the name from Alan into Alby
