Another way to think logically is to ask who would take Pence’s place were he removed.
Answer: Speaker of the House.
Nancy Pelosi.

I think this is an excellent justification for Pence being a good guy. The 3rd in line before would have been Paul Ryan, so equally as horrible.
Q
I think there's some confusion. If Trump and Pence both die or resign or are removed, the Speaker of the House does become President. But if the VP is removed or resigns, the Speaker does NOT become VP. The President nominates a VP, and the Senate has to approve the nominee. Until a nominee is approved, the position remains vacant.
