The Brothers Karamazov embodies basically the best of Dostoyevsky's works. Both are Dostoyevsky's characteristic ideals. He recycled a couple of elements throughout his works. The dream with the spider from Demons is also in A Raw Youth is the best example, because he copied it almost 1:1.

Myshkin was a prototype of Alyosha just as colonel rostanev was a prototype for myshkin.
You'll find lots of great writers do this. It's been said that great thinkers only have 2-3 great ideas that they continue to come back to, elaborate on and improve/clarify.

They're both intended to fit the holy fool archetype. It's not quite the same as recycling characters.

Myshkin and Alyosha are both quite different. Alyosha, while very idealized, is still very human, whereas Myshkin is a Christ-like figure, genuinely too pure for this world (The Idiot is basically about what happens to a purely good soul, i.e., Christ, when he's forced to live among huemans).
