Well, we do not always have control over the actions of others in our family.
Myself, I would not probably have done it, but perhaps they know something we don't.
Granted, Erika Kirk forgave her husband's killer, but that does not excuse him, exempt him from justice, either here on earth or in front of God on Judgment Day. All it does is mean she's not holding him answerable to HER for what he did.
Forgiving someone sets us free from being bound to the offender for the wrong they did to us. It doesn't absolve them in the least.
That said, raising this kind of money so soon, does give the appearance of incentivizing more of the same.
