So many questions on Judas Iscariot

Could he had chosen NOT to betray Jesus since it was "predestined" that he will? If Jesus was meant to die to save us, and Judas facilitated his death, can't we conclude that Judas is a Hero? 

Why do we blame Judas as if he had a choice? Can't we agree that he was created for that mission or else how can we explain the fact that he remained adamant and unwavering despite all the warnings from Christ? Etc. . . 

I have been trying to avoid these questions. They are not easy questions to answer, the reason that any answer opens up another question especially if the person asking you is looking for logical answers that appeal to reasoning only. 

In my philosophy days, I had once asked my professor that if we claim that God knows everything in details before they happen, it then means that if heaven and hell exist, he knows those who will go to heaven and those who will go to hell. . . 

So, those that will go to hell, do all you can, you will still come down to hell. . . 

Can we call this choice? 

If my actions, good or bad, are known in concrete details to God even before they happen or before I was born, can we call that freedom? If two things are presented before me to choose from, does God know the one I will choose? If he knows, cant it be argued that he "programmed" me like that? 

It is like saying that God is just sitting down somewhere and watching all that he had "programmed" before hand as they unfold. 

Well, these questions are not for baby Christians. . . And most philosophers will agree with me that questions are more important than answers. But fortunately, I am not here to teach philosophy. . .
