Perhaps the angry reaction is justified given that the comment implied that “society” should be free to do as it pleases with a person and their property when they die. Most countries today vigorously protect the bodies and property of the dead.
> We, as a society, are free to decide with what's left of you and your belongings
A country can be a society, and if that society decides that its dead bodies and their belonging need protection, then so be it. Doesn't seem like the most beneficial thing to do, but you're free to disagree with me. If a dead person's organs can be used to save the lives of others, vigorously protecting that body seems like a selfish thing to do.
Most western societies have rejected your utilitarian thinking, upholding an individual's choices over any forgone benefit to others. For example, every day people die on organ transplant waiting lists, and every day healthy people die in car accidents, but their organs are discarded because they did not check the "organ donor" box on their driver's license application.

In the context of the comment you're replying to, none of this is reasonable, and some of it isn't even relevant. You should consider that you're forming an emotional, hostile argument.
