Careful, ong... you're dangerously close to my only religious belief:

The only thing that can unequivocally count as "evil" is voluntary ignorance.

Not knowing something is one thing.
Choosing to not know a thing is a completely different matter.

Acting to the best of your knowledge, but making mistakes, is forgivable.
Choosing to ignore what you know is best to do things you know are not best is not forgivable.
