No, Revan got his memories back..went after Kreia(so (s)he remebered who (s)he was)...
Also all the things we find out in K2 tell us about his personality..and it really seems not to matter much even if he was light or dark in K1...
You see,now he has a purpose...
Now he is the old Revan,not your PC..your PC might be just a fade memory for all we know
I'd rather never meet Revan or at least customize him(with llet's say someone aking you to draw him\her)
Or just kill him\her..simple eh...
