Zombi Humor

How does this happen? I watched the first in the epic series yesterday, and one of the main plot points I picked up on was Bernie is...dead... So basically, two douches kidnap a dead guy to have fun. Thats called grave robbing. Is this a behavior we should be encouraging? Whats the justification for why he's not...buried yet? Is Bernie on display in the vatican for 365 days? And is he not starting to rot? I don't see how these guys can justify to themselves this behavior.

"Hey Larry!"
"Yeah Richard?"
"Want to take advantage of that corpse some more?"
"You mean abuse his body, steal his stuff, and generally show disrespect for the dead?"
"Yes I do!"
"But why would we do that?"
"For the money!"
"Oh ok! Lets do it!"

Or I imagine it going something like that.
