Who is the most responsible character? The least?

[Moneybag]

Vijay. Yes, he gave away his control and power to a company and thought his role was over and done with. However, he soon realizes his mistake and tries to help. It is a relatable issue because of the ethical question concerning patient doctor relationship. He takes back the reins and full responsibility. He puts together a a strong and committed team in the end.
Zoe and Demi were great too. Zoe, ignored the signs of possible betrayal but is brave enough to confront the issues. Vik is a disappointment. In my opinion, all the characters had a responsibility towards their actions and decisions thereafter.

Good point
Thanks for the comment

Miles was my favorite.

Vijay is one of my most intimate and morally upright favorites so far, in my opinion. He definitely has a dubious character.

Vijay stands out to me as one of my top personal favorites because of his responsible behavior. However, he does raise some doubts.

All the characters are amazing and responsible but Mile really stand out for me. My least responsible would be those gang stars selling guns and amiunnation.

Several amazing characters, but Vijay is my favourite.

Several amazing characters, but Vijay is my favourite. The gang proliferating ammunitions was my worst.
