Murder
The Bible states that God (the God of the Bible) is a killer; that is true, but according to the definition of murder below, the God of the Bible is not a murderer. Albeit anyone can be accused of murder, even GOD, but proving such accusation when applied to GOD requires the application of a standard, a trial and a judicial decree.
"Murder
is the unlawful killing of another human being without justification or
valid excuse, especially the unlawful killing of another human being
with malice.".- Wiki
