Of course, she wouldn't say this out loud. This thought just flashed through her mind for a brief moment.
In Chiang Xiao's view, Meng Xinian was more suited for going on missions, through gunfire and explosions. It's not that she was selflessly minded towards the world; she just felt that with his skills and personality, that life might suit him better.
It's certainly better than having him sit in an office, flipping through newspapers, drinking tea, and attending meetings.
While he's still full of energy and strength, why not go and spill some hot blood?

Meng Xinian surely must have thought about it like this at some point.
