Oda turning World Government into buffoons where they put more effort into killing their top scientist than they do in trying to kill Robin or Joy Boy Nika. Vegapunk knowing too much information does not mean it's okay to kill him off. This subplot of WG wanting to kill Vegapunk is just Oda's lazy way of writing where he wants an easy path in making Vegapunk another Strawhat ally. And to make it worse Oda sends fodder CP0 with Seraphim to kill the person who created them, that is some great writing there. While at the same time Kizaru and the other admirals are at home sitting on their asses getting high twiddling their thumbs.
It only makes sense if this is a part of the cleansing shit.
When fodders/humanity in general get too advanced, Im/Gorosei decide to do a social reset and kill everyone who are too smart for this era.
Ancient Kingdom probably wasn't ancient but advanced as fuck hence why WG decided to put an end to it so they can keep everything best for themselves and rule over the low iq people.
If it's not and Oda just wants to involve Vegapunk assasination plot then it is strictly retarded but we both know it.
