My welfare matters to me. But I am not alone. The welfare of others is just as much a rightful purpose.

How far does this reach?

We can speak of the welfare of all. That sounds grand. But it is empty. For “all” are not definite people. I can really help only definite people: my neighbor, my friend, my colleague.

And what about right?

Welfare, mine and that of others, is something particular. Right is universal. The two can fit together. But they can also contradict each other. What does me or others good is not right for that reason alone.

Summary: The welfare of others is a rightful purpose too. But the welfare of all remains empty. And what serves welfare can contradict right.
