I'm not going to give my husband's ashes to his relatives that want some
Why won't you give them the ashes?
I don't think they will take good care of his ashes
You should give them the ashes. They are his family and they want at least some of them. It's respectful to share.
I am going to say no and call them greedy.
You can do that but it will make things escalate and cause friction in the family. People will also think you are mean for withholding something so dear to them from them.
