So many people somehow feel dissapoint on this decision, calling Saturn and Kizaru weakling just for that. I want to clear things that I'm sure are litteraly obvious but not for people who build power lvl agenda. What we know about Gods? Gods are not a human beigns, and those who pretend to be a god even One Piece manga litteraly use global Judgement Day instead of killing just some sinners.
For example, Eneru, even when no one was even close to him in power lvl decided to destroy Sky Island, before he saw faced Luffy. Buster Call is another Judgement Day - the day when God's decision will be taken and in global terms sinners will face judgement.
Activating Buster Call doing nothing with Power Lvl and its is just God's decision in global terms to anihilate sinners and punnish them
