Act 4 Cain Issue

ok is there any way to get the soulstone from cain in act 4
because i usually like to do the quest later on down the road
at lets say lvl 70 - 80 ... but as you know cain drops you if you
havnt done the quest yet when you try talking to him...
whats the eziest way to get soulstone because after the first
time passing, mephisto doest drop the soulstone again
some times it lets me get the soulstone from cain but
for some odd reason it drops all my friends...
