Hi, my answer to this questuion is : No, it is not !
Let me elaborate...
Helping is needed by your new or actual team members, because you are their sponsor and responsible for their advancmen. After all, you profit from your team members, the least you can do is to help them achieve what you have also done.
And most of all, they will be gratefull for your services, and probably will stay longer in SFI !
