At the end of the day, Westview residents for all of Wanda's mind-control can go back to their normal lives and contact their family and loved ones. While Wanda lost her family, likely forever. So yeah I think it's fair to argue that Wanda did make a real sacrifice for them even if she did control their minds.
I am kind of amazed that so many people think Wanda is "the next Thanos" for her accidental use of powers she didn't know about or entirely control, while Tony Stark's years of arms profiteering and Ultron-making (which certainly didn't leave many people fit and able to go back to their normal lives at the end of it) doesn't prevent him from being sanctified as a saint.
At the end of the day, Tony killed more people and hurt more people than Wanda did, and that includes Wanda herself.
But that's what happens when a woman gets power. Misuse it once and you weaponize her husband to tearfully go "why did you make me hurt you".
