I don’t like the argument that certain fans use to excuse the Eleventh Doctors actions. That argument being ‘well the Doctor has always committed genocide and killed so stop acting like Eleven is wrong.’ Yes, the Doctor has committed genocide before and probably will again. He has used weapons and violence. They all have. The difference is how it’s done and the consequences after. Often the Racnoss situation is brought up but look, Ten offers her a choice and ample opportunity to leave. Nine and Ten both offer their enemies a chance to walk away. They offer help, they offer to look for new homes for them. Ten goes as far as to become human to try to avoid killing a species. Ten offers to help Davros and Nine can’t bring himself to kill the Daleks in POTW. They so obviously struggle with their decisions and feel remorse afterwards. The companions, like Rose, are sure to tell them when they are wrong and you can see how horrible Nine feels when he realizes what he almost did. 

The problem with Eleven is that he doesn’t seem to look for any other way. He’s so quick to violence and is so flippant about his actions and the actions of those around him. He dances around and jokes with his “wife” about how many of the Silence she can kill to buy them time. His companions are often belittled and never call him out on his BS. The narrative doesn’t even show how wrong his actions are. There are no consequences and it’s never discussed that other ways could have been used, other choices. This is a kids show and they need to be shown and told that even the Doctor can make a bad choice and be called out on it. I just feel like Eleven is often applauded instead of chastised for the atrocities he commits. 

Look, I guarantee there’ll be tough times. I guarantee that at some point, one or both of us is gonna want to get out of this thing. But I also guarantee that if I don’t ask you to be mine, I’ll regret it for the rest of my life, because I know, in my heart, you’re the only one for me.
