We circumcise stillborn babies for many reasons (see e.g., here). Would the same apply for one who it was unhealthy for him to receive a brit milah?
For example, let's say person A's two brothers both died receiving a brit milah. We assume that he too will die from the brit milah and do not give him a brit milah. When he dies, should we give him a brit milah just like we would give the stillborn a brit milah?
