How much grieving does an angel do when they learn that somebody intentionally sins?

I was thinking when people later either denounce God or God turns them over to a reprobate mind if the angels grieve at this. How much does the average angel grieve when learning that we misuse our free will and grieve the Holy Ghost?

Do you think angels tend to grieve after we intentionally sin and if so, how much on average? Please also give your top views on how angels usually behave in Heaven!
