But,,, we do.
Every event has one-or-more 'cause-factors', including a reason.
There is 'no-evil' in nature, all-things-natural.
Evil is a human-invention and has one-or-more human-causes.
Humans may-or-may-not intend to harm or disturb anything.
We may well be unaware of the total-results, total effects of our actions.
This does not negate our responsibilities.
Cause and reason, too often have the same meaning...
