BIBLE TIME: Charlie's murder was a violation of God's divine order, not Erika Kirk's... She sinned against God by forgiving him without his repentence. No theologian would have agreed with the outrageous suggestion that we unconditionally forgive those who abuse and murder our family members.

Whether one can interpret it that way is up for debate, there are valid points on both sides.
Regardless, Jesus forgave the people who put Him on the cross, both Jews and Gentiles, pleading ignorance on their part. So I would say we are free to forgive those who sin against us in their ignorance, and often (see the life of Elizabeth Elliot and others) this will bring about the conversion of even those responsible! See Luke 23: 34 -48 (Even one of the centurions responsible converts, as does a thief on the cross, and the people go home beating their chests as a sign of sorrow! - Israelites and Judeans!)
