This is the same council who poo pooed that the idea the Sith had returned, never mind what Qui-Gon had to report, took a army of clones without seriously questioning who actually commissioned it, and even when tipped off by Dooku, (who they insisted would never try to kill a senator) never suspected Palpatine of being a Sith lord until it was too late. Not the brightest bunch of bulbs in the chandelier. š
No argument there ha ha! But, in terms of training Jedi and vetting Midichlorian-rich children, they had at least been doing this for a long time without noticeable fallout. Otherwise, like I said, there would be scores of self-trained Dark Siders running around Force-choking people and generating enough of a psychic ārippleā to bring the council to attention.
To use my previous X-Men analogy, if Charles Xavier didnāt take on mutant kids, they would then be at risk of a) having no control over their powers and destroying their own lives and b) being recruited into Magnetoās brotherhood. But with Midichlorian-kids itās clear that, if left alone, they pose no threat. Otherwise the Jedi Order would snap them all up on principle. So it follows that training is the key in the SW universe, at least as I see it.
