I don’t mean to butt in (sorry!) but the Indigo tribe is made up of (former) criminals that lack compassion. The power of the Indigo light forces them to feel pure compassion unimpeded by any other emotion. Dick definitely doesn’t fit in there lol.
That’s not true in every case.
See: Ray Palmer.
Also, that particular comment was about Garth, but anyway…
I do know that about the Indigo Tribe mostly being former criminals. However, there are clearly exceptions.
