The idea is for people to think clearly and stand up for what you believe. It’s not necessarily only being dangerous against evil, it’s dangerous against wasting time, not taking care of your mind, body, spirit, money etc.
it’s dangerous against faulty beliefs, false perceptions and things that are not true.
Not necessarily “evil” although that is definitely a piece of it. My father disciplined me as a boy when I was missing the mark and I could have been better. It wasn’t simply when I broke the rules (ie evil)
Dangerous against foolishness and sloth etc.
