Like comp already say. At least with QM we know that the future are 
weighted and free-will will correspond to choosing among normal worlds.
With comp, there is only promising results in that direction, (which 
could lead to a refutation of comp).
John Bell (the physicist, not the quantum logician) has also crticized 
the MWI with respect to free-will, but this does not follow from the 
SWE. The SWE does not say all future are equal. It says that all future 
are realized, but some have negligible probability, and this left room 
for genuine free-will. For example I can choose the stairs, the lift or 
the windows to go outside, but only with the stairs and lift can I stay 
in relatively normal worlds. By going outside by jumping through the 
windows, I take the risk of surviving in a white rabbit world and then 
to remain in the relatively normal world with respect to that not 
normal world. This is why I think quantum immortality is a form of 
terrifying thinking ... if you think twice and take it seriously. Of 
course reality (with or without QM or comp) is more complex in any 
case, so it is much plausibly premature to panic from so theoretical 
elaborations. Actually computer science predicts possible unexpectable 
jump ...
Is it worth exploring the possible comp-hell, to search the limit of 
the "unbearable"? Well, news indicate humans have some incline to point 
on such direction. That could be the price of "free-will". Have you 
read the delicious texts by Smullyan (in Mind'sI I think) about the guy 
who asks God to take away his free-will (and its associated guilt 
feeling) ?
