Oh dagnabbit, this is a fun one.
Of course, murder is bad. But assuming that Seraphim guy actually did drive her senior friend to end it, I would agree with her. If somebody drove a friend of mine to end themselves, I'd probably kill them too.
In the scope of the prison's rules, I think she'll be pardoned. Especially after Gentle's gory death, and with such a sympathetic backstory. What do y'all think?
