i'm a heavy duty roleplayer, a character i make needs to have some thought process to make decisions, so on my last playthrough (this is the one where i went with the secret ending), in my mind (yes call it head canon if you like) v was going over her options, she was about to go with the aldecoldos till johnny pointed out that all she'd be doing was getting all her friends killed by throwing them at arasaka, in response she ponders: "i've only got a few hours to live, not enough time to make a plan, let alone execute one, going in with a small unit under these circumstances doesn't look good, likely get everyone killed anyway, and i'm not going to sit on this roof top and wait to die either, might as well walk into saka tower an try killing my way to mikoshi, at least this way i'm only risking my own neck". and from the dialogue that seems to be a reasonable conclusion to make regarding what v is thinking, what motivation may be lurking under her skin, imho. now, if v was allowed to express concern for the lives of their friends as a motivating factor, seems to me that v shouldn't be railroaded into becoming a jackass concerned only with making it big, in several points during the main quest v was given the opportunity to say basically (i'm paraphrasing here), "yeah, starting out all i wanted to do was make it big, become a legend, now i see it was just a childish fantasy, i'd settle for a quiet life at this point". now, note i said this isn't actually said in game at all, but it's the gist of a few conversation options throughout the game, seeing as v is able to express similar feelings through the game, this v did, so in my mind making it big was no longer a goal to her, and hadn't been for some time. i'm just waking up, sorry if this doesn't track well, just some spare thoughts, maybe i should wait till i've actually woken up to post. lol
