Most people see integrity as weakness and manipulation through deceit as strength. Being able to fool everyone makes them feel powerful, so someone who can't be fooled, such as one with integrity & discernment, makes them feel exposed and powerless, their ego takes a hit, and they hate anyone with it.

I don’t hate evil, or anyone who is. I just don’t trust it, so I stay away from it. Just like I don't hate lies, but I don't trust or believe them, I ignore them.
