I like Gina Gnosia so much because she has a backbone of titanium and integrity instead of blood. When she's Gnosia there is a chance she'll reveal herself so that she can be put into cold sleep – not because she dislikes eliminating people, but because she hates lying. If she is caught as a Gnosia after being declared 'definite enemy', she apologizes for lying. Gina wants to be kind to others, and as Gnosia, does not see sending people to Gnos as contradictory. But lying? Lying is always unkind, and she acts accordingly.
Then there is of course the Big Scene. Gina, as Gnosia, learns the crew is heading to the Allocosia System. As a space traffic controller, she knows ships regularly disappear in that system; she also knows that, due to Gnosia containment protocols, LeVi will not be able to perform emergency repairs should she ship be damaged. Her choices are to protect herself, or protect the crew. Despite being Gnosia she chooses the latter, prepares for a potential hit, and then when the ship takes damage, immediately goes outside to perform emergency repairs. And then, knowing LeVi won't be able to properly repair the ship as long as there are Gnosia onboard, she outs herself as one and lets go of the ship.
She could've asked to be put into cold sleep. It would have required her to come back inside and go through the procedure, during which her emergency repairs could've given out. The most secure way to save the crew was to remove herself from the ship entirely, even if that meant condemning herself tto a slow, painful, lonely death. So that's what she chose to do, even acting as a supposed enemy of humanity. As we learn later, she saved Setsu's life doing so. In Setsu's first loop, where Gina wasn't Gnosia, the collision in the Allocosia System caused them to be crushed.
Gina acts to help others, using the tools at her disposal. When she is Gnosia, this is another tool. If her best way to help others is to send them to Gnos, she will; but if there is a better way, she will do that instead. All this while having the lowest stats among the crew and few special skills at her disposal. I hope everyone spontaneously regains their memory of the loops and crowdfunds a monument for Gina.
