I can't remember a selfless action or deed Anakin made post PM. The slaughter of woman and children. Constantly putting the woman who he loves and is duty bound to protect in danger at every turn. The murder of a defenceless and armless man. The complete disregard for his unborn child in his attempts to save Padme by finally giving in to the dark side. Disloyal and resentful to a man who took him under his wing when no one else would entertain him. Selfish and arrogant (as shown in him ignoring Obi Wan and rushing in to take Dooku alone as one example) Sure we are told he was a good man but we were never shown it. In fact were are shown the complete opposite.
