Bruh. The feels but I'd hate this. An illusion no matter how wonderful is still an illusion. At least a harsh reality means that I can work to change the reality but a perfect illusion is based entirely off of the illusion creator & is, therefore, without freedom. Furthermore, all the pain in life teaches us things -- maybe we don't always learn good things, again the decision to do so is up to us -- but at least we can grow & be different b/c of it; you can't do that in an illusion
I think they all suffered in their own way. However Sakura didn't experience a tragic past. Therefore, her past is seen as less important compared to her teammates. In my opinion, Hinata would've made a better heroine & team 7 member since she was outcasted by her father and looked down on by some of her clan.
