The guy is in an excellent, for his age, physical shape. He can move around, including up and down the stairs, without a cane. It said so in one of the articles I read about him (and provided a link to it).Inconvenience a 94 year old in his final months of life? That'll teach those nazis.
I say that very likely he has still some years to live.
I am certain you would not be that soft on him if he killed your own people, but since that is not the case, you are "lecturing" Poles.
