It does not matter what I, you, or anyone else want. Statistically, if one lives in a malaria prone country the risk to life of having the sickle cell trait is less than the risk of not having it. If one does not have it one has a serious risk of dying or being seriously compromised by malaria. If one has the trait that risk is zero in most instances and very much lower in the remainder. On balance more people die from malaria as a consequence of not having sickle cell than do of having sickle cell, as less than 10% of those with the trait can develop sickle cell anemia.
Repeatdly listing the effects of sickle cell anemia is irrelevant, unless you also list the devastating impact of malaria on those who lack the trait. Would I wish to have sickle cell anemia? Of course not. But would I wish to have malaria? No. And having the sickle cell trait, though it carries a small risk of leading to sickle cell anemia, is protection against the latter. However, the choice of which of these you have is not yours to make. It is down to nature and the genetics of your parents.
