I do think Wanda should be held accountable for her actions. In Civil War it’s clear she’s not ready to be out in the field and so while she did save a lot of people, she inadvertently hurt and killed others. However, she’s still learning and trying to do the right thing and atone for her mistakes.
Wanda is seriously one of the most powerful characters in the MCU. I think she’s up there with Thor and Carol with regards how powerful and potentially dangerous they are. I mean, she held back Thanos who had five Infinity Stones at the time while simultaneously destroying a sixth Infinity Stone! She’s so strong and badass and amazing! But as well as being a badass, she’s sweet and caring and loving too.
I’ve got to take a moment to mention one of my favourite character dynamics in the MCU – Wanda and Clint’s relationship. He’s like a surrogate dad to her and I love how they talk to one another and protect each other in battle. Wanda’s way stronger than him with her powers, but because of her past she isn’t so confident or aware of the world compared to Clint so they can help each other out when they need it. Also, I totally believe Wanda’s has gone and babysat Clint’s kids while he and his wife go out for dinner more than once.
