The fact that an informant gets a benefit by setting you up and testifying in court is something that effects his credibility and pointing those things out might convince a jury to disbelieve that informant. If the undercover agent was present during the "sting operation" won't his or her testimony be sufficient to convince a jury that the person delivered the drugs. Yes a person can be convicted on the facts that you gave but it all depends on what is presented to the jury.
