Christians in the past DID find real verses to justify their horrible actions. To justify the crusades, slavery, beating women and children etc.
You telling me now that’s too vague doesn’t change that it was historically done. That’s the whole point. Different interpretations are used at different times in history to justify whatever suits the people/rulers etc at that point in time.
Plenty of people have used Christianity for evil. Plenty of people have used Islam, Judaism, Buddhism, etc for evil. It’s all the same.
The holy war has been ongoing ever since man has decided there’s a god and couldn’t agree on who he is. It will be ongoing probably for the rest of time for the same reasons.
