Husband wants to name our baby after his Dad

Jessica • Just married, next on the check list... Babies!!
So my husband is very close to his dad and I understand that, however I don't feel comfortable naming our son that when I have a father who was an amazing father to his children. My father in fact has helped us more in our marriage with moving and for the wedding than his father has. In addition, not that it should matter but it's his brothers name too and his brother is still dependent on his mom and dad and is 36 years old with 3 kids. I don't want my son to have his brothers name when I don't think he's a good role model. I've explained that I have a dad too and I don't think it's fair to name our son his dad's name and he says "well my dads taught me everything I know and I want to teach my son the same". I think my dads feelings would be hurt though. Do you think I am a bad person for putting my foot down and saying no? Also his dad's name would be the middle name but I still don't feel right doing so.
