The Sixth Doctor was outraged at his own people in Trial of a Time Lord .
However , not only did his melodramatic arrogance and caustic wit eventually subside , it actually hid the fact that this incarnation retained the Doctor 's strong moral sense and empathy as seen in Revelation of the Daleks in which he showed great compassion to a dying mutant and Trial of a Time lord where he displayed outrage at his own people for their part in a plot and cover-up which resulted in the death of most of the Earth 's population .
