CRISPR has many functions; one of these is that it can be used to treat disease. Scientists who use CRISPR could see editing genes such as ours out of the gene pool as entirely uncontroversial. We are whole beings, with our genetic conditions forming a fundamental part of who we are. Yet stubborn beliefs about “good” genes and “bad” genes nonetheless persist in discriminatory attitudes that affect us both. But we should be reminded that bad genes don’t necessarily lead to bad lives, just as good genes don’t necessarily lead to good lives.
