Do narcissists ever really care about another but blame them if things don't work out?

@Allelse Yep, you got that right.

My mother, older sister and father are ones. Ugh. My Dad has some degree of knowledge, not much, but he hates himself for it while hating everyone else for it, blaming them for everything. My sister knows very well what she is and uses it to her advantage and why not? her ability to manipulate, use and cast people off has become a perk to her. While my mother is more your textbook type who doesn't have a bleeding clue and is 'ALWAYs' the victim.
