Viktor Chemmel is the new “boss” of Arthur Berg’s gang of thieves. What do Rudy & Liesel think of him? Why?

Liesel thought Viktor was a tyrant..... both of Rudy and Liesel thought he was a bastard.

“Do you like him?” Rudy whispered.
“Do you?”
Rudy paused a moment. “I think he’s a complete bastard.”
“Me too.”
