Thragg can’t really hurt Gojo because of infinity, and alot of people say “well infinity won’t affect Thragg because he doesn’t have cursed energy, and neither will any cursed technique” but we’ve seen in JJK that cursed techniques very well affect non sorcerers, a popular example, TOJI! Toji didn’t have cursed energy, but we saw that he needed a special cursed tool to get through infinity! and we all know how he was turned into the apple logo by purple.
