I knew Old Man was a monster, but dang! The man easily toyed with a ogre, the same monster that wiped out a full party.
Also it's within his character to not kill those guys, because he don't know the whole story, even if he's suspecting something, also he's a guild leader, so he's trying to not hurt his guild members without any reason. But I'm sure once he returns if those three aren't killed by monsters, they'll receive a severe punishment and some ass beating too.
