I wonder how Tobirama managed to experiment the edo tensei jutsu while there no genetic clones at that time....

1. They are raised as normal children in the orphanage. They will be trained as normal shinobi for the most case, but not for being expandable pawns for a threat. They will be treated as genins while in Naruto's rule.

2......

3. Naruto did show his disgust. But it's not like they don't need his research and data.

Plus, for me, it seems they let Oro be with his experiments as a token of gratitude for his services in war.
