Which do you think is more harmful ignorance or apathy?

As bad as these things are I happen to think these concepts are interesting. Ignorance is not being knowledgeable or unaware of something and Apathy is lack of interest or indifference which is basically not caring. They say ignorance is bliss where in some areas it may seem like that but that isn’t necessarily true considering ignorance just feeds the bad things that are happening. Apathy definitely has its negative effects as well considering it also just lets things escalate. Which do you think is worse?
