You should probably read up on the lores. Yes, they let in clearly evil people, but the League is the most powerful platform for spreading influence on Runeterra, and it makes the conflicts controllable and systematic. It's a dangerous gambit, but it's a much better option than the alternative.

There's no real direct comparison to real life events, but the Rune Wars and its effects are somewhat similar to the two World Wars and the outcomes of using nuclear weapons. That's why to prevent a nuclear war and thus mutually assured destruction, both sides fought each other in proxy wars across other countries to spread their influence. Countless people died as a result, yes, but it was a better option than complete annihilation. Ironically, so was the option to develop a nuclear weapon in the first place.

As for champions who have no real affiliation with any of the established countries or have a nebulous objective, the recent champions are not the first; Rammus, Wukong, Jax, Gangplank, Sona, and just about anyone from the Shadow Isles are but a few examples. I think the idea is that having enough wild cards would prevent any one established political force from becoming too powerful and upsetting the balance, and ultimately risking another Rune War. Besides, no one in their right mind would do anything to upset a legion of powerful mages, summoners and champions, who could easily obliterate any rogue element too powerful to allow to function outside of the League. It sounds a bit stupid and absurd that mortal enemies like Demacia and Noxus would ally together in that scenario, but such things have happened in real life.
