Well this post is a little heart breaking..
With that said though, I do understand why some people may not like Jackie, I mean we are all different and all have our own opinions in life.
I'm surprised that anyone can come to a conclusion with the character given the small amount of development he got, he deserved a lot more to his story. With the whole montage and the fact that it was clearly noticeable that both Jackie and V knew each other long before the events of CP2077 (it was especially noticeable during the Corpo life path).
I can only assume all of this will come with dlc and/or an expansion. Though it should of come with the base game as the story feels rushed without it, terrible decision in my book.
I did find it strange with Jackie that his whole personality at first did seem like he was rather loud, then during the Heist he then changed to being a bit more paranoid as if reality had finally sunk in. This was noticeable and did make me feel a bit different towards him. As if all of his confidence was for show.
However, I personally like Jackie myself. Despite being a pussy cat sometimes he did seem like a loyal friend. Caring to everyone around him. Also, despite how much he deep down might not of wanted to do something, I do get the feeling he would still put his friends and family first and thus do it anyway. For example during the Corpo run he deep down didn't want to help V with his/her problem but I do believe if the whole thing didn't end up giving us a rather abrupt ending, Jackie would of helped V regardless. I liked this about him and the scene where he practically chased off the Corpo goons during the life path really nailed it for me.
