(Feel free to move this if it should be in Ethics and Morality instead.)
Now before you say "God would never do that!" keep in mind that in the Old Testament, there were several times where God commanded entire cities to be destroyed and killed, including the infants. And disobedient children were sometimes stoned to death due to not following the Fourth Commandment (at least of the group commonly called the Ten Commandments. So as much as we may try to ignore it, if we go by the Bible there was a time when God commanded those things.
So even if you say God wouldn't do that now, it's clear he did at one point (and thus he could again since he's the same through time, right?). So, would you be willing to draw a heavy metal sword down upon the tiny body of an infant newborn if God commanded it? Even disregarding modern times, say if you lived in that time period and God asked you to do that, or stone disobedient children in your family or group. Would you do it?
Ok... I see a immediate problem with your suggestion.

My Response: God didn't command godly people first of all to destroy certain cities such as Sodom and Gomorrah, it's not like he had christians do this. Now sure in the OT some godly men went to war...but that's different I believe then one your suggesting and we don't live in a time like that anymore where you fight for territory and such so again this doesn't apply.
IK you have a response as to those who would suggest God wouldn't do that... but again the examples you give are all OT. And I believe the verse with the stoning you are referring to is this one.
Deuteronomy 21:18-21King James Version (KJV)
18 If a man have a stubborn and rebellious son, which will not obey the voice of his father, or the voice of his mother, and that, when they have chastened him, will not hearken unto them:
19 Then shall his father and his mother lay hold on him, and bring him out unto the elders of his city, and unto the gate of his place;
20 And they shall say unto the elders of his city, This our son is stubborn and rebellious, he will not obey our voice; he is a glutton, and a drunkard.
21 And all the men of his city shall stone him with stones, that he die: so shalt thou put evil away from among you; and all Israel shall hear, and fear.
But we should remember that rebellion is as witchcraft, or described that way in the OT it's not a light thing. Also they were under OT law and capital punishment, and as much as I hate to say it capital punishment back then was more based off what God desired rather than just humans (government we have today doesn't factor in God). SO again... this wouldn't apply becuase we have a government that operates under different man based laws.
ANd sure God is the same yesterday today and forever....but it's clear his manifestations and way he operates isn't. We can easily just take a look at how salvation changed through the bible as a prime example or the manifestation of the son of God aka God in flesh in the NT vs like a cloud in the OT. OR even the church in the NT vs places of worship in the OT. Or the NT scripture itself vs the OT scripture.
Also your question can't really be answered... we would be under a different set of laws, have a more harsh view of disobedience, and yeah different life, honestly I would say if I loved God/feared God as I do today... i'm sure I would do it. If I have that same desire to do what God says no matter what at that period of time I am sure I would obey him and follow the laws of the land.
Then again though God puts all of us in certain times for a reason... maybe I wouldn't be willing to follow his laws, maybe I would revolt or something. Maybe in a different time period I wouldn't survive. That's another thing that makes this question really impossible to answer lol.
You should maybe have asked if killing someone even if it was lawful/ordered by God or whatever was justifiable. Or something like that.
