I beg to differ. As revolting as their actions were, it is hard to consider 10 year olds as adults and treat them as such in the eyes of the law. The recidivism you raise could actually support my argument rather than strengthen yours. Had they been treated differently (I.e. more as children) perhaps they might have been rehabilitated and ended up more “normal”.
Don’t misunderstand my position. What they did was vile beyond comprehension, but were 10 year olds fully responsible for their own behaviour at this age?
