I gotta say, you really dont have any shame.
I went with your definition, not mine, for the sake of the argument. Based on your initial challenge, I knew you thought they were asking for it/deserved genocide, because people dont say what you said otherwise.
Its honestly abhorrent that you would even think like that. Which again, casts serious doubts on your judgement and ability to understand what valuing life really looks like.
The amalekites were a people that the author of 1 Samuel felt was an existential threat amd evil--deserving of genocide. Based on what we know (which isnt much), they were a people in the area vying for the same resources that the israelites were vying for.
Human life begins in the womb, but there isnt anything really notable until the 13th week or so, when natural miscarriage risks go way down. Between 50 and 80 percent of fertilized eggs dont even attach to the uterus, and 40 to 50% of those that do nauturally miscarry.
