There's usually no ship I'll object to unless it's morally wrong.
(This ship is from Your Turn To Die)
However the only ship I will physically recoil to is SaraGin, or to be honest any ship with Gin because he is a literal child.
However I'd say especially SaraGin because oh my god I just want to enjoy their platonic, almost parent/son and or sister/brother relationship. Please, familial bonds, even if not blood related, are good for Sara to have so she doesn't go insane. Making that romantic is a next level of gross and disturbing!
