At first, God sent Cain away for murdering his brother Abel. Now, after Christ has ascended, God sends His sheep away when being mistreated.
Some use James 2:13 for the excuse.. "For judgment will be merciless to one who has shown no mercy; mercy triumphs over judgment." for judgment without mercy [will be] to the [one] not having shown mercy. triumphs over mercy judgment. The one who has no mercy towards others will not be shown any mercy either... When time for Judgement comes, those who showed mercy will be rewarded over those who showed no mercy yet judged. Believer or not.
