This is a jukugo word that uses the on'yomi readings of the kanji. You haven't learned this reading for 悪 yet, so here's a mnemonic to help you:
When you feel disgust for someone all you can manage to say when you see them is, "Oh... (お), it's you." Feel the anger when you see their face, "Oh, you again. Bleh."
