Being against (what you believe to be) murder should be very easily distinguishable from being in favor of whatever flavor of welfare program you're thinking about.
So, applying that consistently, if you believe that fetuses are people, the question would be - are you ok with people being able to make legal ("state-sanctioned") choices that result in the death of other people? And of course we all are ok with that to some degree - driving is legal (40k/year dead in the USA), as is gun ownership (30k/year), as is deregulating the EPA (unknowable but large numbers of cancer deaths), and climate inaction (unknowable and growing numbers of climate related deaths).
As must be frequently pointed out, well over half the deaths by firearm in the US are not the killing of other people, but suicides.
Of the killing of "other people", I'd wager a minority of those are associated with legal ownership - prior surveys of inmates in the US in prison for gun related offenses (not just homicide) show a great portion (40+%) obtained the gun used for the offense from an illegal source.
I'm guessing this representation of illegal ownership goes up when you filter for just homicide offenses (the killing of other people) and when you consider whether the possession itself was legal, even if obtained from a legal source.
Manslaughter or the killing of other people outside of homicides/suicides are in the low single percentage digits of the total figure.
The reason for the trigger pull, it turns out, matters quite a bit to people.
