I Most certainly do not believe in universal salvation. No, the Father does not compromise with sin and neither will he tolerate its ultimate end. He has sent his son to effectively reverse the sin of Adam in creation. Though he has tolerated it (sin) for some time now, he will not allow it to ultimately destroy his creations.
But, again, as the Trinity is a relationship of love and thence created man in its image Genesis 1: 26-27, a relationship of love, creating a relationship (humans/Trinity) in love, and this condition of love is demonstarted throughout history as the Father is seen to initiate the healing, calling, guiding, reproving, disciplining, scolding and yet, always because of love and the intrisic qualities of love that he alone holds as described in 1 Corinthians 13 to a degree that we can not begin to achieve.
