Oh, please, don't think I'm making any excuses here .. but I was around and about the evidence management side of a five deep dive into institutional childhood abuse ... the various things that went down tend to explain a lot of early following behaviour once some kind of distance from early abuse is made.

You're right to flag ongoing and persistent shitty behaviour as unacceptable - even assigning blame there gets problematic as there absolutely is an element of "would they be less bad had they had more support on escape", but you can't be giving a pass forever.

Bloody Trolley problems .. this is one of several areas with no good choices, no easy solutions.
