Oda delayed about Vegapunk's Satellite revival just to put them into the same chapter Saturn that dies. This shows that good people willing to sacrifice themselves to protect people that they think will change the future for better, they won't fear death because someone who shares similar view will come to carry on their legacy and their good deeds will guarantee their reincarnation. On the other hand, evil people will sacrifice anyone for themselves, they fear death because of losing power and status that are too great and dying like the others that they despise, someone with different view will come and replace them.
