[Batman] Why did the Kane family allow Alfred to raise Bruce and keep the fortune?

Alfred was a bodyguard and a butler. He never had children of his own yet he was trusted to raise one of Gotham's elite children by himself. 

Martha's siblings could have raised the child in a healthier household. Even if the will stated that Alfred would be the caretaker, why didn't  the remaining family contest this? 

Bruce could have been raised with his cousins. He could have been raised in a military upbringing and perhaps been better than this playboy persona we see today.

It was stated in Thomas and Martha's will that Alfred would look after them. Martha's brother toke on the company finances and Alfred raised the boy. They probably felt it was best as Alfred was already a familiar figure in Bruce's life and played a large role in raising him before his parents death.
