How do you know there is any less or more malicious intent than is expressed by some on this board? Malicious intent is a definition of this world. As your definition shows, it has nothing to do with how God's word defines murder.
Malicious intent is defined clearly by God's Word.
Malicious intent to cause death and the penalty is clear in this passage:
Numbers 35:16-21 NAS77
16 'But if he struck him down with an iron object, so that he died, he is a murderer;
the murderer shall surely be put to death.
17 'And if he struck him down with a stone in the hand, by which he may die, and as a result he died, he is a murderer;
the murderer shall surely be put to death.
18 'Or if he struck him with a wooden object in the hand, by which he may die, and as a result he died, he is a murderer;
the murderer shall surely be put to death.
19 'The blood avenger himself shall put the murderer to death;
he shall put him to death when he meets him.
20 'And if he pushed him of hatred, or threw something at him lying in wait and as a result he died,
21 or if he struck him down with his hand in enmity, and as a result he died,
the one who struck him shall surely be put to death, he is a murderer; the blood avenger
shall put the murderer to death when he meets him.
Those words are nestled between provisions for cities of refuge for a person who unintentionally causes the death of another. Refuge did not mean that the offender was no longer responsible for their deed. It meant they could not be killed without due process.
Numbers 35:10-15 NAS77
10 "Speak to the sons of Israel and say to them, 'When you cross the Jordan into the land of Canaan,
11 then you shall select for yourselves cities to be your cities of refuge, that the manslayer
who has killed any person unintentionally may flee there.
12 'And the cities shall be to you as a refuge from the avenger,
so that the manslayer may not die until he stands before the congregation for trial.
13 'And the cities which you are to give shall be your six cities of refuge.
14 'You shall give three cities across the Jordan and three cities in the land of Canaan; they are to be cities of refuge.
15 'These six cities shall be for refuge for the sons of Israel, and for the alien and for the sojourner among them;
that anyone who kills a person unintentionally may flee there.
Numbers 35:22-24 NAS77
22 'But if he pushed him suddenly
without enmity, or threw something at him
without lying in wait,
23 or with any deadly object of stone, and without seeing it dropped on him so that he died,
while he was not his enemy nor seeking his injury,
24 then the congregation shall judge between the slayer and the blood avenger according to these ordinances.
