Well he has to do things in order, or else, "converged". I said he could destroy the time machine papers without saving Kurisu by letting Kurisu dies the same way he saw it but takes the metal upa beforehand.

He can't change what already happened because he has the memory of it (Kurisu's "death"). What already done can't be undone. Which is why it's also important the original Okabe at that time has to see Kurisu lying unconscious in pool of blood so the loop is kept.

If he tries to change the way things worked, he will make the original Okabe at that time gets different experience than August 2010 Okabe, he'll deny his own memories. Which i think, you can't deny what you already observed, trying to do so will make the attractor field "converges" on things to keep your past memories intact.
