“ If the user is in no actual danger, such as if their opponents have no true malice and are just trying to help, then the Quirk won't be triggered.” So you could still be potentially harmed by traps, by sedatives (to tie you up and experiment on you), and many other possibilities. You should go for the spider bite. Feel free to let Peter get the bite, too, but you should acquire a better danger sense. Spider sense is true precognition.
