One of the many downsides of the Hail Mary being a suicide mission is that Armando is likely only equipped to keep astronauts alive for as long as they're useful to the mission.
Obviously this is going to be reflected in the amount of painkillers and general medicines he's been supplied with— enough for three astronauts to last several months to a few years max— but also… there's really no point in keeping any of those astronauts alive after they stop being useful to the mission.
Grace finds this out when he gets to a certain point in his starvation on the journey to Erid and, instead of offering medical advice, Armando announces that Doctor Grace is far too sick to continue being of use and so it’s recommended that his fellow crew members euthanise him to save on resources.
That is. Not a good day for shipboard morale.
