Sure, if a marketer is truly trying to help the consumer make informed decisions -- making an earnest attempt to help interested consumers find the product/service that's right for them -- then they'd be good, not evil. This is, if a marketer: 1. is truly trying to help the target make the best decision, including going with a competitor or simply not buying anything; 2. won't even try to sink the target's attention unless they have good, informed reason to believe that the totality of their offer (including relevant costs, time, and effort) is expectedly a net positive for the target; then they'd be good and not-evil. That said, advertisers who seek to push products indiscriminately would be evil. The allegorical used-car-salesman who pushes a vehicle that they know to be worth less than they make it out to be, or seeks to trick the buyer into spending way more than they need to, is harming their target for their own self-interest; seems like simple predation. That said, not all marketing is simple predation. For example, some offers are for legitimately useful products that a non-trivial portion of the target-audience could quite plausibly benefit from buying. Such marketing can have elements of good mixed into it, too.
