It seems that most people, whether they be religious or not, believe in something called evil. The problem is, there is actually no such thing as evil because “evil” is really nothing more than an English word we use to label an action or experience which we perceive in a negative way. If nobody had emotions or the ability to feel discomfort or pain then nobody would believe in evil. This goes for good as well, by the way.
One key to understanding all of this, at least from a Christian perspective, is to remember is that evil and sin are two completely different concepts.
You have one part of your assumption correct. Their is no such thing as evil if your trying to think of it as a force that is opposite of good. Evil in essence the absence of love.
Their is only one true force, feeling or emotion and that is love. All other feelings, emotions, forces or whatever we define it as, are just a perversion of love. Hate, anger, fear, greed, joy, jealousy, etc, are dependent on love.
A good analogy would be that is no such thing as darkness. Darkness is not a force that is self-generating, it only exists because their is an absence of light.
The is no such thing as “evil”, people always go for the good (what they think it is the good, they might be wrong and kill people, but we´re none to judge, we´re all humans and we make mistakes and we should help each other). There´s just good and people in constant growth.
In the logical sense there´s no such thing as evil. Anyways keep on thinking like that and don´t ever give up (i went crazy cause i wouldn´t believe in how the world doesn´t value our beings, but i don´t recommend you to go crazy, you´ll learn a lot but i´m not happy, but you are still in that amazing point) Anyways keep strong and you´re more qualified than a lot of college teachers
