Holy Grammar, Batman.
I do think that a lot of the shinobi world's problems would stop if dudes just f***ed more instead of obsessing over "power" and crap. Tiny d**k syndrome, perhaps? Think about it. Madara, Obito, Kabuto, Orochimaru... all these people needed to get laid. The only "villain" I think probably was getting laid was Nagato (Konan). Funny enough, to me, he was the best enemy of the series. His story actually raised sympathy, unlike Obito's Rin bs, Madara's "I had the chance to bring peace to the world but instead chose to enslave everyone" and Orochimaru's... umm... nothing? Orochimaru had no reason to be evil. Just a straight up psychopath, which makes his current good guy attitude inconsistent.
Nagato was a somewhat rational dude, with a sexy female sidekick, and had reasonable motive. Also, the whole "create a tailed-beast weapon to stop wars" was not only plausible, but it was relevant to a real world, paralleling atomic weapons and raising the question of whether it is ethical for them to exist. The Japanese must have a particular connection towards this topic.
OT: a lot of characters never had offspring. Tobirama, for example, or any of the Sannin. We never met Hashirama's son/daughter, a half Uzumaki half Senju who would presumably be an amazing ninja, but oh well. I'm sure we'll get a time skip at the end where most of the current jonin/chunin have kids.
