Thanks Team Duwang for the batch and your hard work as always. I really don't want this manga to end, it's been fun sharing the experience with everyone.

Close, but I'm pretty sure Eko was resolved to die, she knew she was never going to get away from the attackers. The gamble was whether or not Souichi would survive the attack as well. People in the studio managed to intervene and save the baby, so she lost. She definitely intends to die; she says that if she accepts her karma and is killed by the people whose lives she ruined, maybe the fact that Souichi will kill Tatsuki will disappear. She is resolved to accept this fate no matter what, but believes that if Souichi is truly extraordinary, he would survive and live on.
I think the reason Eko believes destinies can change is because she had originally forseen Tatsuki's age of death, but when she became pregnant, her visions changed so that Tatsuki would die earlier than her initial prediction, and it would be directly as a result of Souichi's actions. In trying to die, she is trying to avoid her second vision, and either A effectively "choose" Tatsuki over her unborn child, or B accept all the karma and misfortune onto herself instead of onto Souichi and Tatsuki. I think in death, she sees all of Souichi's possibilities before him, implying she thinks he does have choices and different paths for his life. Remember that Eko is an admitted fraudster; she probably only believed some of what she was telling people, not all of it.
I don't believe Tatsuki knew exactly what Eko was planning; he just said she looked like she was planning something. Tatsuki seemed very much like someone who admires the strong doing what they like in life, so he probably had no intentions of stopping whatever she wanted to do. Remember, he admired Kyara for being strong enough to just do what he liked, which is one of the reasons he stepped down to become a ref and accept that karma onto himself. He also believed Souichi was extraordinary, so even if he knew she was trying to kill him, he probably figured Souichi would survive.
I think Souichi does indeed believe in a destiny of sorts. Being from the Kiruma bloodline he probably did not require any extra prodding from Eko to believe he was great, the entire power of Kakerou was pretty much at his beck and call since he was a child and knew he would ascend to the position of Leader someday. His belief in a kind of "destiny" was probably reinforced when he gambled with Fukurou. If he had won he would have abandoned Souichi and continued living as Hal. But he lost, and since Eba was able to reimprint on him, he probably believed that he must live as Souichi (until he lost his memory again). That being said, with the way he's talking, I don't know if he's trying to convince Baku, or himself. I think he still has doubt in his heart about it, and repeatedly kept expressing to Oofuna and Baku that he was hoping to live as Hachina and Hal just a little bit longer before StL.
