A list of those royally screwed by Danzo.

[LoZelda101]

Danzo provided the story with plot (non-reincarnation plot), he did Kishi's dirty job and what did he get? He was Murdered by Kishi

he killed himself. not so bad

 

[Mad Titan Thanos]

Great thread with manga facts

 

[Nick01]

Selfish as hell.

 

[Sonzumaki]

Let's not forget the little frog he straight up murdered during the invasion.
