It almost sounds like Zen samurai-mentalities.. Maybe Type 8s can become more healthy through the art of the samurai.
But really.. There's nothing wrong with those qualities, and looking to them. There's a balance with everything. Puppy mentioned 8's having to notice that what drives them is also what can destroy them.. this is absolutely true. It's almost like having an absolute power.. At the risk of sounding like I'm in a movie or something, I don't think type 8s are totally healthy when they indulge into their type completely. Finding any description of a "great leader" from others will give you the type 8s at their best. Uncorrupt, ideal, just, kind, honorable and respectful leaders can give off an innocent, yet courageous vibe that can make others go "Ugh.. what a chump." But really, these ideals are what keep us tamed. We want to lead, in some shape or form. Finding good leadership strategies, and using them with everything we do in life, helps keep us at peace.
Like I said before.. my thought was that these just sound SO impossible and comic-book-like, that striving for them would almost set us up for failure. Type 8s are probably WAY more often average-health than they are healthy.. It's a daunting task to say "You'll be healthy when you're a perfect leader or have the qualities of superman." The description is an ideal shot for from way afar.. but I think it ought to be more down to earth and attainable. No one will be able to completely agree to or be compatible with a majority of the description without being self-absorbed and delusional to an extent. We'll always fall way short of that post.
As far as this "Fe" debate on those bolded texts.. The description is assuming that the 8 wants to serve others and be a part of society.. but it's saying that, I feel, because type 8s DO have a desire to leave their mark on people or their environment in some way, shape, or form. It's difficult to find a type 8 that wants to be reclusive from society because of that. They don't want to be harmed or controled, they want to be the one pulling the strings. It's a lot of potential responsibility.. not being drilled into whats best for society is like asking someone selfish to take command of an area. It IS assuming whats right or wrong for society.. but As type 8s, we need to acknowledge that we need that. We always know what's best for us, or so we think.. so we need to invest more time into what's good for others and how our actions impact them.
