Does Ethical egoism requires we have the kind of disposition which is incompatible with our having a healthy personality.
None of it. Ethical egoism is not synonymous with the doctrine "whatever you can do is morally permissible to do." Ethical egoism is the doctrine that you ought to do what is in your self-interest. The use of force, even to gain something that you want, may not actually be in your self-interest, hence it may not be permissible according to ethical egoism. The question is: Are there any rational constraints on self-interest?Chronos said:What part of ethical egoism is not the same as might makes right?
