My guesses would be these, you can add your thoughts or an opposing point if there's one. WARNING: a mention of, well, using Death Serum on oneself.
Peace Serum
I don't really think any other faction would approve of it- Candor would view it as deceptive, Erudite as impairing mental abilities, Dauntless as cowardly/escaping into comfort, and Abnegation as self-serving. But there's a possibility Erudite and Abnegation would resort to it if it is in any way practical or helpful for others.
Truth Serum
I think only Amity would be strictly against it, as they are against saying things that might cause confict. Abnegation's view would depend on the use. Dauntless would like that it results in people being open, but would dislike that they needed the serum to do so. And Erudite would approve of it as it reveals information.
Memory Serum
I think only Amity would approve of it as it removes bad memories and feelings. Dauntless would find it cowardly, and the other two would disapprove of erasing information.
Death Serum
Amity would dislike it for obvious reasons. Abnegation would in the same way, they might accept using it on themselves to help others, although they do view suicide as selfish. Candor would probably depend on the circumstances. Dauntless could view it as brave and/or necessary to use either on oneself or another, as they view killing.
Simulation Serum (the variation with fears)
Candor and Erudite could like the information it gives about someone, and the latter would also value the psychological knowledge it can give, but then they both have reasons to dislike such direct contact with strong unpleasant emotions. Amity would definitely dislike it for that, and Abnegation additionally because it is self-centered.
Paralytic Serum
Erudite would value its practical use. Candor would probably dislike it simply because they dislike the feeling. Amity could use it as a physical equivalent to Peace Serum that works psychically, and when used on them they would maybe mind less than others, along with Abnegation, as both are passive and discouraged from complaining. Dauntless would maybe disapprove the most as they are very agaisnt passivity in many forms.
If you have any other thoughts, I'll be glad to hear!
