Personally, I think the song is about lonliness/discrimination.
People are treating him like he's subhuman or something.He feels alone, betrayed and etc. which is why he's questioning whether or not he should continue to love others and even questioning whether or not all these people who discriminate against him are right and that he's perhaps a freak of some sort and shouldn't be treated as an equal in society.
