In that case sane vampires include; Mannfred, Vlad, Isabella, Neferata, Aborash, Whalach Harkon, Luther Harkon pre-lizard trinckets, Gashnag the Back Prince, every Lahmian and Von Carstein secondery vampire in Ulrika's book series, the Silver Prince of Marinburg and the Red Duke all just of the top of my head.
Explicitly mad vampires of the top of my head: Konrad, who was mad before he was transformed; Urshoran, after his country was destroyed and other traumas; Wor'soran, Melkior and Zachrias the Everliving, who are all Necrachs.
Apologies for any misspellings.
