“wrongful conduct,” bad acts, and misfeasance. J. Goldberg, A. Sebok, & B. Zipursky, Tort Law: Responsibilities and Redress 31 (2004). Some level of blameworthiness is therefore ordinarily required. But, again, if aiding-and-abetting liability were taken too far, then ordinary merchants could become liable for any misuse of their goods and services, no matter how attenuated their relationship with the wrongdoer. And those who merely deliver mail or transmit emails could be liable for the tortious messages contained therein. See Restatement (Second) of Torts §876, Comment d, Illus. 9, p. 318 (1979) (cautioning against this result).
For these reasons, courts have long recognized the need to cabin aiding-and-abetting liability to cases of truly culpable conduct. They have cautioned, for example, that not “all those present at the commission of a trespass are liable as principals” merely because they “make no opposition or manifest no disapprobation of the wrongful” acts of another. Brown v. Perkins, 83 Mass. 89, 98 (1861); see also Hilmes v. Stroebel, 59 Wis. 74, 17 N. W. 539 (1883); Duke v. Feldman, 245 Md. 454, 457–458, 226 A. 2d 345, 347 (1967). Put another way, overly broad liability would allow for “one person [to] be made a trespasser and even a felon against his or her consent, and by the mere rashness or precipitancy or overheated zeal of another.” Bird v.

Moreover, unlike its close cousin conspiracy, aiding and abetting does not require any agreement with the primary wrongdoer to commit wrongful acts, thus eliminating a significant limiting principle. See Nye & Nissen v. United States, 336 U. S. 613, 620 (1949).
To keep aiding-and-abetting liability grounded in culpable misconduct, criminal law thus requires “that a defendant ‘in some sort associate himself with the venture, that he participate in it as in something that he wishes to bring about, that he seek by his action to make it succeed’ ” before he could be held liable. Id., at 619 (quoting Peoni, 100 F. 2d, at 402). In other words, the defendant has to take some
