In a civilised society, we don't typically regard 15 year olds as responsible for their own radicalisation at the hands of adults

There is no civilized society that treats 15 years old not responsible for joining terrorist groups and for actively working with them.

15 year old being radicalised into terrorism is a societal and parental failure, not the moral failure of an individual child. We don’t treat 15 year olds as adults in other legal proceedings, we should not do here either

Civilised societies tend to blame the groomers, not the victims.

I thought the right wing supported that view.
