@geoxile Paid for completing the mission of killing the goblins. He clearly is thinking they're incomptent but he's not going to go out of his to save their ass as clearly shown later in the story. He's a mercenary that has been through a party wipe before and it's clear he had enough confidence to get out of the situation if he had to.
Also set them straight? Okay he voices his opinions more harshly and they refuse to listen then what? He's stuck there with them cuz he has no money to go back unless he walks which would take time and he has no money for food etc etc. We don't know if he has the skills to live in the wild while traveling back to town and even then he is broke.
Like try to actually understand circumstance before you go on your little tirade.
