See, I don’t think that Compassion is just a feeling.
Compassion is an old, sad demon which possesses you and feeds on your heart. He makes you feel the suffering of someone else; in fact, he makes you share it, in order to make the original suffering lesser. He doesn’t offer you much comfort. He doesn’t make your life better. He might bite too hard sometimes.
But in case you feel his bites, you’re still human.
