Loving one another means recognizing that everyone has an equal opportunity to be loved by God. Many petty annoyances can keep us from this reality. That said, there is no place in Scripture that asks us to accept or chase after evil doers who try to harm others. In fact, many places in the Bible tell Gods people to “drive them out”. We are allowed to mistrust, move away, drive out, etc, those who embrace evil, the only thing we cannot do is deny them the opportunity to recieve God’s mercy: ie, condemn them. Death is not the final solution, judgement is, and it is completely up to God, not us.
If you look at the parable of the prodigal son, the father did not go out after the son, and he let him go away to do his evil deeds. Clearly, he did not stop loving him, and most likely prayed for his conversion. But it is the REFORMED son he welcomes back, stating that he was dead, and is now alive; once lost, now found.
IMHO we need to pray for those who are dead and lost, but keep them at arm’s length for the sake of the common good. We must always hold out hope for them, and work to save others from a terrible fate by spreading God’s word, holding out the opportunity for mercy and recognizing that we cannot save everyone: the choice is theirs alone, as the final judgement is God’s.
