Unconditional love only applies to those incapable of willful violation, willful harmful crime, and anything willfully evil.
Unconditional love is for the innocent. There's no legitimate law against innocence. Innocence is that life that never ever has malicious intent.
Mercy and forbearance for that mercy otoh, is based on a condition of genuine repentance to enter into love. That's because innocence cannot coexist with enemies of such innocence.
In Judaism, Islam, and Christianity love is based on conditions of accepting specific things for mercy.
