Aah, but the loving God created hell, so consider this explanation:
God could not force people to return His love without abrogating their humanity. If God were to zap ungodly souls, it would be tantamount to forcing conversions at gunpoint, which would not be free and genuine. If God were to prevent people from behaving hatefully, then He would need to prevent them from thinking evilly, which would make human souls programmed automatons.
MFW only exists when there is the possibility of choosing between two qualitatively opposite moral options that we call good and evil. These options are opposites because of essentially different consequences for choosing them. Choosing good results in blessing, life and heaven; and choosing evil results in cursing, death and hell (Deut. 30:19). This is why hell as well as heaven exists. It is the just consequence for choosing evil rather than God. The Spirit of God is good: love, peace and joy (Gal. 5:22-23). Therefore, whoever rejects the Lord is spiritually separated from Him (Isa. 59:2) and thereby chooses the evil or satanic spirit of hatred, strife and misery and reaps the just consequence called “hell” in the afterlife (Gal. 6:7-9, Heb. 9:27-28).
God created theoretical evil or the possibility of rejecting Him as an option that actualizes MFW/free human personality. As such it is necessary and even good (Gen. 1:31). Of course, it was wrong for Satan (1John 3:8) and humanity (Rom. 5:12) to make evil actual by choosing to Sin or reject Faith in God’s Lordship. The first people to choose the evil option were named Adam and Eve (Gen. 3:6). Sin: ignoring God/God’s Word.
God loves a cheerful giver (2Cor. 9:7), which means He desires people to cooperate with Him happily because of love and gratitude for His grace rather than to cower before Him because of fear of hell. Love must be evoked; it cannot be coerced. And again, when souls sin or do NOT choose to love God freely, it is perfectly just (loving and logical) for them to reap the appropriate consequence (Gal. 6:7-9) or hell.
Such evil people punish/torture themselves by experiencing delayed karma, just as those who experience appropriate justice during this earthly existence also punish themselves or reap what they have sown and send themselves to jail. This view makes souls responsible for breaking the rules rather than blaming evil on the judges (or Judge) who enforce the rules. The purpose of earthly punishment is to promote repentance, but the reason for retribution in hell is to attain justice. It is difficult to imagine, but somehow even someone as evil as Hitler will receive perfect justice, perhaps experiencing the agony of the millions of deaths he caused in accordance with the principal of “eye for eye” (MT 5:38), after which their souls are destroyed forever (per John 17:12, Rom. 9:22, Gal. 6:8, Phil. 3:19, 2Thes. 1:9, 2Pet. 3:7 & Rev. 20:13-14).
Thus, hell is an expression of God's love for justice.
