it does matter...after the epilog and talking for the last time with the drug dudes there is a hidden video for sabal or amita.

-you find sabal on the tempel island killing the followers of pagan.
-i'm still searching for amitas end sequence, i want to know if she's crazy like sabal. 

if maybe some of you guys found the spot already,pleas tell me^^ otherwise i have to fly to all 150 sites to check (

through the game i always found sabal had the bether reasons but after all sabal is just a power hungry lunatic, i'm so curious if amita is also.
