every day tf2 fans prove that they are not capable of intelligent thought.
"he'd flee for the hills for someone else" literally the whole point of the comics is that he eventually came back to his team out of his own volition once he found out miss pauling was getting them back together. if he was really only using them for his own means, there would be no reason for him to come back to them, he could have just left them dead in the dust instead of needlessly going against cheavy's orders and facing his rage.
why would he put himself in danger if his actions were purely self serving. the only reason he "fleed for the hills" in the first place is because the team disbanded and he needed money, not because he actually had a secret plan to betray them once they were no longer useful. literally all the mercs went their own separate ways once mann co was supposedly done with, so why does medic always get the most shit for finding the most convenient means to assure he can still do his job and earn money to survive and fund his research at the same time lol. and that's not even getting into the fact that he outright told sniper he was happy to see him.
if he had no care for them beyond being experiments, he would not have gone behind the classic team's backs and blown all their paychecks on reviving his former teammates who were tehnically his enemies at the time. why would he do that when he had the classic mercs to experiment on. he had all the resources right there.
you are factually incorrect, medic literally calls sniper and demoman his friends in the comics.
he also smiles at soldier twice in expiration date, he is clearly on friendly terms with people unless you give him a reason not to be.
there's also the fact that miss pauling canonically hangs out with him, as per her contract lines.
look at that! it's almost as if he has friends and people that he likes and cares about and enjoys spending time with. genuinely why is this so fucking hard to understand. it's literally plainly spelled out in the text. do i have to hold your hand and explain this to you like you're five.
