Is that moral? Is it just? Is it love? --------- Most definitely! Even those that have been slandering God due to their ignorance and lack of faith can be forgiven in just the same way Paul was.
(1 Timothy 1:12-14) I am grateful to Christ Jesus our Lord, who imparted power to me, because he considered me faithful by assigning me to a ministry, 13 although formerly I was a blasphemer and a persecutor and an insolent man. Nevertheless, I was shown mercy because I acted in ignorance and with a lack of faith. 14 But the undeserved kindness of our Lord abounded exceedingly along with faith and the love that is in Christ Jesus.
