Now, it seems a common thing in fiction for immortal creatures who have done something really nasty to be locked up forever, but is that really fair?
Would it make more sense that you serve, say, 30 years for every person you eat, so a monster from beyond the stars that eats 20 people gets let out after 600 years, provided it behaves itself in prison?
Now, you could argue that for mass murder, you never get let out no matter how long you live (or that monsters from beyond the stars are dealt with under different rules), I guess, but I'm not sure about that.
(Also, how do you rehabilitate a monster from beyond the stars that's been in prison for 600 years?)
ETA: Not necessarily demons of any particular religion or aliens, they were just the first examples I thought of.
