its not really any big of a deal for oro to come up with 2 resurrected people.....you guys act like it would actually be of some sort of inconvenience for oro to fulfill his end of the bargain if he regains the use of his limbs from the only person who can do it.

besides, all 3 sannin are pretty much independent of their villiage, its just that oro wants to destroy it while the other two just keep to themselves. Jiraiya seems to have a sense of responsability for looking out for konoha, but the other than that they dont really seem to know of any real sides of any sort of battle, and so there isnt reason them to go backstabbing each other like you guys suggest oro would
