In my personal opinion I personally agree morally she’s in the grey area and often walks the line between hero and villain. In her villain moments (with the best examples really being WandaVision, Multiverse of Madness, and Age of Ultron) she was sort of droven to those given her trauma and severe lack of therapy. In Age of Ultron she was was driven to join Ultrons group and Hydra with the main want of getting revenge on Tony Stark after a war he funded/ weapon his company made caused the death of her parents/ childhood home. In the ensuing battle Pietro dies which immediately adds more trauma to her belt. Then a year later thrusted into CW where she was concluded as a monster due to lost of control over crossbones which caused her even more trauma given how the world sees her, and vision being her only real home/ love and his eventually death her being blipped her coming back and her grief being manipulated by Hayward, severe lack of therapy and real healing from one trauma episode to the next made her breakdown in west view make sense and letting her grief take hold she just wanted her family really same in MOM just she’s corrupted by the darkhold and her grief is displayed more. Her actions are brought on by the ends justify the means mindset it seems similar to when she says to Strange that her sacrifice meant nothing in the grand scheme of things in her mind seeing her life was the only one in the multiverse that was the screwup I can see where it drove her motive
