Look it’s hard to say if it saved lives in the overall ww2 tally, but surrender to save lives was the rationale of the Generals eg in The Netherlands. They looked at what the Luftwaffe had done to Rotterdam, looked at what weapons they had themselves, considered the prospect of what was going to happen to Utrecht next, and decided that further resistance was futile. https://en.m.wikipedia.org/wiki/Netherlands_in_World_War_II#German_occupation
I didn’t think it saved lives, since it empowered the Nazis to kill more people. So I say no it wasn’t the right choice.
