It's not that I don't understand why humanity prioritizes the negative over the positive. It's that I wish I didn't. I refuse to acknowledge my understanding for it.
The way my mind understands, and realizes why it's important that I do understand, and my desire to remain blissfully unaware of the reasoning behind people's desire to hurt others are at odds. You could consider it toxic positivity, but that understanding leeches away anything that could've made it acidic. Kindness without that understanding is kindness without a reason, and that makes it an empty action. Like receiving empty words from someone you know doesn't feel the way they should. Even if they mean well.
That is why I cling to the hurt of this world, even if it hurts. It makes any action I take to help others that much more meaningful to me.
