Evil is an objective term as people come with different moral reasoning. What one might consider evil is what another might consider neutral or good.
Although, there are some “evils” that can be widely agreed upon as a problem. This type of evil is fine, as in it often leads to people coming up with solutions on how to fix the problem.
Then there is the objective type of evil that becomes a bigger problem. When two groups disagree on what to consider evil, it often turns a simple disagreement in opinion into something that hurts and destroys.
The problem of evil is in the consent itself and the fear that it brings along. Evil is such a broad term that anyone can call anything evil. The belief that we must destroy and accuse those who we deem evil is what brings more bad or “evil” into the world.
