if i recall it right, ruthless chapter 1 has one 3 choice prompt that determinates what ending you get, except if you are particularly evil, then you get the 4th ending no matter what.
there are two diverging initial routes. "You look like shit" and "Are you alright?"
For the welcome ending, Choose "Are you alright" and then "deceive the deciever". Make sure you do not send Asterion into the valley too much as you will get D&S.
