When you shun a person, you are forbidden to be kind to them. You can't even say "Hello!" or check to see if they are doing ok.

Galations 5:22,23 NWT: " On the other hand, the fruitage of the spirit is love, joy, peace, long-suffering, kindness, goodness, faith, mildness, self-control. Against such things there is no law."
and
Luke 6:27-37 NWT: But I say to you who are listening, continue to love your enemies, to do good to those hating you to bless those cursing you, to pray for those insulting you. To him that strikes you on one cheek, offer the other also: and from him that takes away your outer garment, do not withhold even the under-garment(). Give to everyone asking you, and from the one taking your things away do not ask them back. Also, Just as you want men to do to you, do the same way to them. And if you love those loving you of what credit is it to you? for even sinners love those loving them. And if you do good to those doing good to you, really of what credit is it to you? Even sinners do the same....To the contrary continue to love your enemies and to do good and to lend withour interest, not hoping for anything back, and your reward will be great, and you will be sons of the Most High, because He is kind toward the unthankful and wicked. Continue being merciful, just as your Father is merciful. Moreover, stop judging , and you will by no means be judged. and stop condemning and you will by no means be condemned. Keep on releasing, and you will be released."
