But I guess for prioritizing the happiness of the friend group, some amount of ignorance is needed if someone in the group is ultimately going to model the world on "they kill and deport or they don't" given enough information to make that declaration, and eventually a person on the other side is encountered?

I understand that some things can be more important than just having fun though, down to personal values.

"To be ignorant" sounds like a moral failing on its face, but I feel it is increasingly becoming required in some circumstances with the explosive amount of information available to subscribe to nowadays.
