The people in the comments can only think in of classes such as strength, and that's where the error in thinking lies. As ScreenRant has clearly described, Sentry's strength will not be enough to defeat Carol.

It comes down to more than just strength. You're just powerscaling kids.

Mar-Vell had a long rivalry with Thanos. It would be a very good idea to increase this with Carol since she's practically a Celestial and Marvel set up a rivalry here between Carol and the Slayer of Arakko aka Uranos.
