You are picking on Jews when thats not really the case. Its for EVERYONE to have a fair chance. Its not the Mormon church that started all that. Jesus himself said that He was the only way...
It all depends if one believes in Jesus or not. If Jesus really is who He says He is, then thats the way it is.
None the less, its completely up to the individual to decide for oneself, either here, or later. No one can chose for someone else, and no one can take away one's agency. THAT is a core principle of LDS doctrine.
Mormons don't believe as soon as you die kapoof one turns into some great being. The same person you are here, you will be there. The trick is learning to be obedient to the laws of heaven. One must know the law of heaven and abide in them.
As far as condemning goes, no one can condemn anyone else. If anything one condemns oneself.
