has the doctor always been morally ambiguous or is this obsession with making him edgy and dark a 21st century thing..?
In the first Doctor Who serial he kidnaps two teachers and attempts to murder a man with a rock.
The third Doctor went to an alternate dimension where he was the fascist running the world. The 4th Doctor performed a coup on gallifrey. The 6th Doctor strangled his companiion and risked turning utterly evil and 7? Do not get me started on 7
In short yes, he has always been morally ambiguous.
Seven destroyed Skaro. Like straight up blew up an entire planet. Only wait, no, he didn’t. He tricked Davros into doing it. He manipulated one of his greatest enemies into burning ALL of his own shit to the ground and when Davros begged for mercy, Seven was all “lol bye” and left Davros to cry over the atomized remains of his home and legacy.
Man no wonder that guy snapped and tried to annihilate all reality.
