The reason why 自分が is there is to make clear who the subject of 情けない is, as nekojita-san pointed out. If 自分が isn't there, it can be misinterpreted as 彼が情けなく思えた. The subject of 思えた is ALWAYS the speaker, thus, even if it's 彼が情けなく思えた, the one who feels he is pitiful is "I". We can't know what others think except in novel-style writings, as you've no doubt already learned.
