He abandons Harry in his 4th year when his best friend has been entered in a dangerous tournament. He abandons Harry again in DH when he is best friend is trying to save the world. He suspects Harry of having an affair with Hermione even though Harry has been his best friend for years. He hurts Hermione when he knows she loves him by snogging groping Lavender in front of her at every opportunity. Even though he has done this he has the gall to tell Harry who is a perfect gentleman to not mess with Ginny. He is an asshole for me.
