Good thoughts, both of you. Good thoughts, indeed.
However, did it ever occur to you that it could actually be the other way around? For some people, abandoning their friends is a really hard thing to do, but for others it isn't. If said person were to take the path of revenge and neglect his/her friends easily, wouldn't that be the weaker path? Suppose it were the other way around, then saving your friends would be the weak path, since you're so attached to them.
My point is that which path would make you weaker or stronger here is relative. Before you bring it up, yes, Kreia does explicitly 'say' which path is which, but remember that she is a compulsive liar and manipulator.
