Plenty of false Christians have said that God's love is not unconditional, that God doesnt love evil people.
God himself says in the Bible:
"Love is patient and kind; love does not envy or boast; it is not arrogant or rude. It does not insist on its own way; it is not irritable or resentful; it does not rejoice at wrongdoing, but rejoices with the truth. Love bears all things, believes all things, hopes all things, endures all things. Love never ends"
Further, God in the Bible says:
"Anyone who does not love does not know God, because God is love."
“But I say to you, Love your enemies... so that you may be sons of your Father who is in heaven... You therefore must be perfect, as your heavenly Father is perfect."
As we can see in this verse, God loves his enemies and expects us to love our enemies.
"The Lord is good to all, and His mercies are over all His works"
"If your enemy is hungry, give him food to eat;
And if he is thirsty, give him water to drink"
