While ‘bad’ leaders can include incompetent, oc­casionally self-indulgent, and lazy leaders, an import­ant special category of leader has long been estab­lished in the literature for those whose egotism and ill-will toward others have corrupted ‘good’ leader­ship norms. Such behavior is generally called toxic. This essay further builds on that analysis by exam­ining leaders who are not simply occasionally toxic, but whose whole agenda is to fan division, hatred, and malignant collective delusion. The article first examines good leadership using servant and resil­ient leadership theory. Then it provides examples of varying degrees of toxicity based on eight elements in which good leadership is perverted. Finally, the ar­ticle looks at President Donald Trump as an example of ruthless rapaciousness and whose tenacity (re­silience) enables him to maximize his toxicity over time – vampire leadership.

弹性领导者的黑暗面：吸血鬼领导

虽然“坏”领导者可能包括无能、偶尔放纵和懒惰的领导者，但长期以来，文献中已经为那些自负和对他人的恶意破坏了“好”领导规范的人建立了一个重要的特殊领导类别。这种行为通常被称为有毒。本文进一步建立在该分析的基础上，考察了那些不仅偶尔有毒，而且其整个议程是煽动分裂、仇恨和恶性集体妄想的领导人。本文首先使用仆人和弹性领导理论检验了良好的领导。然后，它提供了基于八个要素的不同程度的毒性示例，在这些要素中，良好的领导力被歪曲了。最后，
