Like his predecessor, this Doctor was capable of boundless enthusiasm, though in his case often at inappropriate times. While many Doctors have intentionally flouted social conventions, the Tenth seems to be genuinely surprised when he is rude or uncouth. Charismatic and manic and with boundless energy, he retained and even exceeded his last incarnation's capacity for righteous anger, especially when Rose was threatened, as when the Wire stole her face. When driven by anger or righteousness, he would act without hesitation to strike down those who opposed him; for example, he toppled the regime of Harriet Jones with just six well-chosen words after she committed what the Doctor considered mass murder.

The Doctor also showed his anger when he gave each member of the Family of Blood an eternal punishment, fulfilling their wish for immortality in a twisted way .

While he had resolved much of the survivor's guilt felt previously, he is beginning to feel his age and, behind the outward playfulness, he feels a deep loneliness. His keen sense of loss leads him to empathise with those who have also suffered.

An undeniable shadow has been cast over the joviality of the Doctor. He had a ruthlessness, bordering on arrogance, that was almost eerie to behold. Beneath his youthful veneer, the Doctor is a very old man who has seen many terrible things; and in some matters, his patience has worn out.

He used to have so much mercy. Now they get one warning.
