Amaterasu never has killed someone on panel, yet you called his GG move. Sure honey, keep lying to yourself. We have seen characters more than once being able to get rid off Amaterasu with ease, even with all that as hot as the sun, and ones it hit its target consumes type of thing. The only time we actually saw amaterasu effectively killed someone was a piece/snake of Orochimaru. Naruto was even able to block it with his chakra, and Wanda's shield are reactive, they're just there protecting her even from stuff she cant see.
Amaterasu is as hot as the sun < Characters had time to react even after being hit by it and come up with a plan to get rid of. They're barely shown suffer from it.
Amateraru is GG > No one killed by it in manga or anime on panel.
Nice try. This one goes to Sasuke for popularity, not because you can actually be objective. That's all.
