Q&A: Does knowing if life is pre-determined or not change anything?

If you think about it, how does the knowledge of how we make decisions really effect everything?  If life is pre-determined for us, then we don't have to worry about making decisions.  But might consider suicide if they found out, but they would only commit suicide, much less even think about it, if they were pre-destined to do so.  If we make decisions purely based on our free will, then we'll keep moving through life making decisions. We won't become any 'freer' or suddenly break any chains that binded us.  Regardless of the ultimate truth, nothing would really change.  That's not to say that is makes the search for truth any less meaningless.
