Having a sense of entitlement on something that is not your own is a very bad habit that needs to stop for whoever is engaged in such.

Like your friend who got angry with you because you stopped sending him money for transportation shows how short sighted he is because this is what you worked hard to earn but decided to help out of goodwill but still it wasn't appreciated.

In regards to the property issue it is rightful and lawful the property of the wife and children should the husband die because they are his family whom he had brought to the world and cherish aside from this mother and father.

Even without a stated will the property which the man's has painstakingly accumulated,worked hard to achieve was mainly and solely because of his wife and children so I think it should rightful belong to them
