It only makes sense that the show continues with the characters in the title.

Whatever legal controversy that is going on that have not even been finalized shouldn't affect the work of someone who is doing character voices. 

We don't have to make a Hitler out of everyone who allegedly committed a crime . If we do that we rob actors of their origins. 

I'd rather have humans who have made mistakes creating and working that people who have never lived through darkness trying to be funny.
