[White Silver King]

I dont think it makes any sense at all. Though, to be frank, I dont think it makes any sense that he even forgave Ultear. She drove him insane with mind magic and pushed him to enslave his best friends so he could wipe out almost the entire planet to bring Zeref "back." He even killed Simon because of her, which is something he still cant forgive himself for even though it was her fault. But Im not surprised, if everyone could forgive that psychopath Laxus then its set in stone that ANYTHING in FT can be forgiven.
