God does things in accordance to the Law set up, humans are subject to Covenants granted. And there will be a final judgment by Law and Covenants.
Of course, God loves His sheep such that His sheep whose names are written in the Book of Life will finally be saved, as for those wolves and goats...do you expect Him to break His own Law and Covenants to show His mercy? (instead His mercy has already be shown through Christ Jesus and the eternal Covenant)
Regarding to the Covenant, what nullifies Jesus Christ's sacrifice is the "no hell" doctrine. It is because no hell and everyone is saved that no Jesus is actually needed. Jesus Christ thus saves noone (you are saved anyway with or without Jesus. That is, because God will not put anyone to hell, that everyone will not suffer even without Jesus. That is, the word "save" is totally meanless as noone will suffer). When this doctrine is legalized even inside the Church, this abomination (denial of Jesus Christ and the Holy Spirit's work) will cause desolation (souls become unsavable thus no harvest) as Jesus is nullified hiddenly.
In an isolatoin from God after the Judgment, humans (the dead) will no longer humans. They are the hopeless. Just like how the fallen angels turned themselves into the devils, humans will turn themselves into monsters. That's naturally what will happen in a (any) place without God's teaching and guidance. And the burning hell awaits.
It's all about His Law and Covenants which is purposefully made to protect His sheep (not the wolves nor the goats). The wolves must be separated as their sinful behavior by their freewill will hurt those sheep. While the goats think that they don't need the Shepherd, they think that they survive the wilderness without the Shepherd, they think they can deal with the wolves and thus choose to live a captive life. They themselves will finally surrender and become part of the wolves. God's setting up of Law of Covenants are all for His sheep (even the wolves and goats part is designed to be all for the good of His sheep in eternity).
