For Magellan, many character reasonings abound.

First, he did defeat Luffy, Ivankov, and Inazuma. That's pretty powerful. Many of the prison escapees were quite a bit weaker than those three, so of course they would run away from Magellan.

I do think the more powerful escapees such as Crocodile could have taken on and possibly beaten Magellan, but I think in Crocodile's case escape was his only intent, and he viewed Magellan as just a simple pest, so he didn't bother to take him on.

This is totally baseless, but it's my explanation
