if you say there is a god running the show that concerns itself with you, then there is a god running the show that concerns itself with you. you can't just turn it on when good things happen to you, and turn it off when it doesn't suit you anymore.
if we say there is a god running the show and concerns itself with human beings, then yes, we have to admit, in some sense, this god must have wanted to allow beau biden to have brain cancer, let it be treated, then let it ultimately kill him and let his father grieve over him. this is an extraordinarily evil way of thinking and talking. and we have to admit that, for the better part of human existence, this IS the way people under religion thought. it is also worth condemning on this board, precisely BECAUSE thousands of people in the 80s-90s thought that HIV was a judgment from the divine for immoral behavior, and thousands died as a result.
now let us make the opposite assumption and say there is no such thing. all questions immediately evaporate. as mammals, we are subject to the laws of biology and evolution. when the molecular machinery responsible for programmed cell death occurs, you get uncontrolled proliferation of immature cells. hence, cancer. when this occurs in the central nervous system, you get brain cancer. this process doesn't know that joe biden loves beau. it doesn't know that beau is a father and a husband and a son. it doesn't care that he's here, won't care if he leaves.
and people who want to be serious better learn to have this conversation. current data is that 1 in 2 of us will have to deal with cancer in our lifetimes. the second scenario, by the way, is also the only game in town when it comes to finding a solution for cancer, which it has, with say, hodgkin's lymphoma.
