IN-GA being destroyed was kind of out of left field, but it felt like a James Bond movie (which was the point). There was sex with a high ranking woman who was then killed, a ridiculous villain, and he got to bed the girl while his driver ignored it up front in the pilot's seat. They wanted to re-create Bond, they kinda got it.
Perfection is a lifelong pursuit requiring sacrifice. The only way to get it quicker is to sacrifice the most.
