There is no number of foreigners that is unacceptable to sacrifice for a middle class livelihood. Anti-cop because they can imagine a scenario where a cop inconveniences them.

Basically ya. If you truly understand what you did was evil you wouldn't ever demand someone forgive you. You do good things as much as possible and if someone decides to forgive you you thank them and keep doing good.

Of course I support outreach to people trying to redeem themselves. Organizing good things for them to do is of course a solid plan.
