Evil exists! But it is something that is on a scale, as everything else is, too! At first, everything is neutral!
Your eye is what makes it evil or good!
>The eye is the lamp of the body. If your eyes are healthy, your whole body will be full of light.
And evil can not be destroyed, it lives and changes like everything else!
If someone is, in your eye, evil but he is more good than others, than he is not that evil as the other one. Hence, he is better!
The Universe is big! There are, as I see it, places full of joy, where evil is something that we (Humanity) would see as not so bad and there are places where this shit here could be seen as a great place to live!
You choose your side! And the ride will go on, lead by rhythm and the cause and effect of your own life!
