Who was the most foolish ruler of all?

[Rune Son of Bjarne]

Turgon!

What a foolish elf he was. . . First he builds Vinyamar and settles there with his people, he is told to secretly build a new city. . .this must have been really tiresome work and it must have gone really slow as they could not just all march there and start building. That would surely have been discovered.

When in Gondolin, because he does take proper security meassures his sister dies. . .He does not give order to pick up Hurin and so his location is discovered.

But the thing that makes him so foolish is that he goes through all this trouble to please the Valar and then he does not see it through. . .that does not make sence. The his people have laboured in vain and not only does it make him foolish it also makes him selfish. His people died because he found Gondolin ever so pretty.
