You are my heroLook I not a pervert or anything like that, I am just contemplating all alternative lifestules.

Well, as Schierke now can enter the armor and help Gutts, the story may get more weird than we can thinkAs SK said the prolonged usage of the armor will take things away from Gatts. I just wonder how much it will take from him. Plus at this point he seems to want to settle down and just protect Caska. How can he if he must use the armor more and more plus the part of his psyche that wants to continue to just destroy....

He does have some feelings. He does not express them verbally, but you can see it in his gaze when he talks to Gutts and Zodd.SK has no real urge to destroy everything, but he is no longer human, and he probably has no feelings and stuff.
One particular scene is one of my Berserk all-time favorites. In vol26, when Gutts wears the Berserker armour for the first time, Zodd turns to Skully and says something along lines 'you make him take the same path as you?'. Then Skully looks at him. That gaze! I once counted it among my favorites Berserk quotes, it says so much!
