When Jesus was on the cross, the Father ...His Father, looked away. Many people look at why?

Some people have said that God is too holy to even look at sin, and Jesus became sin on the cross ...so His Father could not look, and that's when Jesus spoke, "Why have you forsaken Me?"

Well, perhaps my understanding is not as mature as others ....but, by putting down my thoughts, it may help me reason it out. (And I trust you won't 'put down' my thoughts.)  

It seems to me that if God can't look at sin, how does He, and how has He judged it.  Adam and Eve didn't say, "Who told you that?  I know you didn't see it."

When people say all our sins ...past, present, and future, were placed upon Jesus on the cross, do they take that to mean that He felt our sin?  I would say that He felt our sin from the very beginning.  The Old Testament of the Bible shows that our God is a caring and compassionate Creator.  For those who think otherwise, what does the verse "Jesus wept", mean?

I would think the worst part is not our sin, but our neglecting to come to Him for forgiveness.  So, why do we neglect to come to a loving Father?  Is part of it ...because we don't want to accept what He would desire for us to do?  To ask for forgiveness requires that we admit we did something wrong.
