So, calling these people worse than Nazis would actually be accurate?
...Oh wait, these people haven't tried to genocide an entire people (yet), so, hrm...
Crap, how do you quantify just how bad people are?
To be fair, the majority of German soldiers during WWII weren't genocidal monsters. So yeah, I think it's reasonable to say someone who would torture a cat to get at his/her owners is worse than Nazis.
