Being a nihilistic and purely resistance/terror 9whatever you like) organisation, it needs oppression, misery and despair among the people to thrive and receive their support. Hamas fears economic developement and better life for Pals in general. Of course they want Abbas to make utterly stupid moves that will destroy the prospect for this for Pals in WB. If Israel lifts the blockade of Gaza and starts allowing economic developement in Gaza, it will create the beginning of the end for Hamas.
