In defense of my favorites, there is a phrase known as 'choosing the lesser of two evils', which, as I believe applies to Tar-Miriel. I read the fanfiction where she and Pharazon did what they did in order to prevent the possibility of civil war, and I agree with that headcanon.

Beruthiel was abused by her husband, which is also someone else's headcanon that I accept. In fact, it was that headcanon which got me thinking about this stuff in the first place.

And Maeglin was tortured by the enemy and broke down, plain and simple. Same old, same old, maybe, but there was nothing insidious at work there. No unhealthy obsessions, no throwing children into furnaces. Alternatively, he might have been possessed by Melkor or Sauron and forced to do these things against his own will (another headcanon I agree with)
