I always see people who thank the darkness, who say they're 'dark', yet I don't see anyone thanking the light. Without the light, Darkness wouldn't exist.
A lot of times people will say "Darkness is beautiful" because the night is when things are quiet, and calm, or I have seen some who claim the Darkness made them insane and they "love" killing things, "being evil", and more.
Darkness isn't the opposite of light, darkness is light, and light is darkness. They are from each other and they need each other to exist - there is balance.
I don't see how one can love the dark yet not also love the light in return.
