Jehovahs Witnesses do not kill others in warfare however, the not "eating" of blood /animal sacrifices interpretation completely misses the point and has not relation to blood transfusions.
So the Governing Body does sanction killing in the name of Jehovah against their own members.( in the thousands now since this policy was introduced in the 1940`s/50`s )
Fathers ,mothers sisters brothers children ,no one is exempt.
Whether it is self inflicted or by another person death is death .
Apparently the shedding of Jesus blood in his sacrifice at his crucifixion/death on a torture stake was not enough for Jehovahs Witnesses they want more blood shed.
Islamic people kill not only themselves but also innocent bystanders Muslims or not randomly in the name of Allah
Again ,fathers mothers sisters brothers children ,no one is exempt from their slaughter
