Still doesn't matter. Since I am predestined by God to either be saved or not saved, however I act is also part of that predestination. Who are you to say that God has not predestined "bad" people to go to heaven? After all, only God can truly know who is elect, correct?
Your argument that good acts are an outward manifestation of being one of the elect is really no different than the Catholic doctrine that good works are part of salvation. They boil down to one statement: Good Christians do good things.
Um, the elect have to be Christians, and since they are Christians, the Holy Spirit lives inside of them and changes them.
You can't be a "bad" person (i.e. non-Christian if I think that is what you are getting at) and be elect.
