That nobody has been killed or seriously injured yet by these people is simple luck. It is only a matter of time before someone is killed who either found themselves in the wrong place or dies trying to fight one of their fires.
And I think it is unlikely he will serve the entire eight years.

No he won't, but the 3-5 or so years he spends there are going to seem like decades. This will either break him or turn him into an animal.
Kinda fitting if you ask me.
