In my story, a minor/secondary character has been introduced to the story. A Russian commandant. No name is just Commandant. He is currently in command of the convicts. He's not a bad guy. Just sort of mediocre I guess. Anyway, I thought of having him die by the real villain of the story. The Russian colonel. I was thinking of having the colonel do it because he doesn't want to share his immortality with anybody. His motivation is well, greed. I thought of having him die, the colonel, of some rare disease which he is wanting to be immortal. What do you think?
