It's not murder equivalent though. You probably have this image in your mind of a fully formed fetus when in actuality its something smaller than a pea by the time like 99% of abortions are done. There is no mind formed, the whole "heartbeat" thing was a lie, it was essentially the cells forming parts and doing basic tests on them to see if it works yet. Your logic would also dictate men NEED to have kids every moment because sperm only lives for a day or so and if they don't fertilize then it's the same as a mass murder (even though only one sperm survives fertilization, so still mass murder).

Also what about future possible kids? If you plan to only have a set number of kids, and aren't in a good place, financially, mentally, or otherwise to have them right now you are looking at two possible options.

Option one: have them now and ruin your, your spouse, AND the kids lives by raising them without funds and before living life and maturing into a better person and parent, and in situations of stress like that you end up yelling at them unjustly, hitting them, or otherwise taking your problems out on everyone else (intentional, or not. Directly or not). Not to mention the overworking hours to pay for them takes you out of their lives when they need you most.

Or Option two: wait until you are ready, financially, mentally, or otherwise and give that same number of kids the life they deserve. And you all get to have much happier lives.

Now in both possible universes the same number of lives are born, and even if you picked universe one, now you've deleted the kids in universe two. So it's still removing their futures.

There is no logical, or even ethical, reason to prevent abortions other than to control women and hurt children. Period. Anyone who says abortions are bad are hateful anti-human or anti-thinking people who want to push themself into others lives and force them to live how they demand.
