Of course, Shigaraki and Izuku remind me of Mahito and Yuuji. (Ignoring hori's obvious influence on gege's characters) They are much alike, both on opposite sides of the same coin. Reflections of each other. For some reason, it's intersting to me to think of Shigaraki as being relgious, holding some sort of trauma to it. I don't believe that it would be any actual religion but just.. religious feelings..?
