AB,
Because if ever you did think about it beyond the superficial level you demonstrate here you'd risk finding out that the reasoning on which your certainties rest are sand - and you cannot allow even one grain of that sand to be removed for fear that the whole edifice would topple. At heart that's why your uneducable - the cost of finding out that your faith beliefs are wrong is too high.
Just contemplating why you, and others, seem to be in denial of your obvious freedom to consciously choose what you want to do.
Could it be that you are afraid of the implications of admitting to the reality of the existence of human freewill?
Implications which would mean that you are personally accountable for what you choose to do?
And that you would have to admit that the ultimate source of your freedom to consciously choose is beyond anything which can be defined in material terms?
And that it would open up the probability of your own spiritual nature?
And that it would lead you to admit the probability of God's existence?
But you should not be afraid of these implications.
You should rejoice in your God given freedom.
Because the truth really does set us free.
