There is a lot of evil in the world. And the more you see it, the more overwhelming it can be. Especially as you become aware of evils that most people willfully ignore.
It’s important to see the world as it is, and to take everything seriously. And that means facing the evil fully, and getting past pretending it’s not there.
But… the evil is not the only thing. There is good, too. And it’s ok to love things, and people. It’s even ok to like things, and enjoy lighthearted entertainment. Even though the world is a mess.
Being happy in a broken world isn’t a moral failing.
