Like Aljazeera, Al-Arabiyyah justifies the murder of the Birri family members

Al-Arabiyya just justified the murder of the Birri family members in Aleppo by saying: that the family is "pro-regime".  They keep repeating that they are "pro-regime".  So the whole family is "pro-regime"?  Does that not basically say that the blood of every member of the family, even women and children, is spillable?  They brought an opposition figure and he justified the murder.
