"What if, Neville Longbottom's parents weren't tortured by death eaters? Basically if Neville was raised by his parents and not his grandmother"

I feel like Neville's personality would defiantly be different. Since Neville and  his grandmother thought he was a squib I feel like he really doubted himself and wasn't that confident, but I feel like he's parents would have been nicer about it. In the Deathly Hallows Neville really worked hard to fight the evil teachers and to not let Voldemort win. I feel that Neville didn't want Voldemort to win because Voldemort hurt him. He didn't want any other kid to have they're parents traumatized like his parents were. If his parents were never hurt then I feel like Neville would still have fought but I don't think with the same intensity and I don't think he would've charged at Voldemort like he did in the Deathly Hallows. Neville was alway's sweet nice and I'm sure he would be even if his parents raised him but I don't think he would've been as close with Luna.  Luna was peculiar or as some people called her "looney" and that made her stand out. I feel like Neville liked Luna because he too felt like he stood out. But if he was raised by his parents I feel like he would have more confidence in himself from the beginning so I don't feel like he would be as close with luna.

I didn't talk this over with my friend so she deserves some recognition:
