I get it's not balanced around that, but I thought I'd throw out the suggestion. Maybe make different intensity options like "Gene Tear" or something. Like each option has a different chance of lethality, but also a different chance of you getting the exact gene you want from the operation. Like maybe one has low possibility of death but also a high probability of getting a ♥♥♥♥♥♥♥♥♥ of junk genes alongside the specific gene you were aiming for, if you get it at all, prioritizing negative genes. That way you still get the gene, but implanting it in someone can prove a more long-term problem than simply killing someone to get their genes.
