WARNING: The following contains spoilers for WandaVision Episode 5, “On a Very Special Episode...,” now streaming on Disney+.
The fifth episode of WandaVision does a good job of setting up Director Hayward as an antagonist. He seems eager to misunderstand and misrepresent Wanda and her choices, with Jimmy Woo reminding him that his assessment of Wanda's past involvement with Hydra is an oversimplification. Meanwhile, Monica Rambeau has to be the one to insist that Wanda isn't the threat he's making her out to be.
However, to support his claims against Vision, he makes a big deal out of the footage of Wanda breaking into S.W.O.R.D. facilities and stealing Vision's body from the lab. Most, if not all, of the gathered SWORD agents seem surprised by the reveal that their organization had Vision's body in the first place, suggesting that it was a need-to-know project, so only people close to Hayward knew the truth.
It seems strange that the footage is from nine days ago, but Hayward has either just received the video or he's waited until now to share it with the others. S.W.O.R.D. has been involved in the Westview situation from the beginning, so it would make more sense for them to have shared this information as soon as possible, so they'd know right away that Wanda took Vision's body. The only explanations for this late reveal are that Hayward somehow didn't know that this happened -- which doesn't make sense as S.W.O.R.D.'s director -- or he knew but chose to reveal it at the perfect time to villainize Wanda.
Director Hayward also glosses over the fact that S.W.O.R.D. had Vision's body in a laboratory. Vision was technically a sentient weapon, which would make him S.W.O.R.D.'s purview, but it doesn't make sense that the Avengers would hand his body to an outside organization. While S.W.O.R.D. was founded by Maria Rambeau, who was close to Carol Danvers, the Avengers only met Carol after Vision died, so it seems unlikely Maria would use that connection to obtain his body for S.W.O.R.D. It could also be assumed that if the Avengers went to the trouble of retrieving Vision's body from Wakanda, it would probably be to properly lay him to rest, like they did for Tony Stark.
If, for some reason, the Avengers decided that Vision's body should be experimented on, it seems unlikely that they would outsource the job, even during the Blip. Tony Stark could have done it, especially since his lakeside home seemed equipped for the job, and Vision was partially his creation. Bruce Banner also had a hand in Vision's creation and could have run the experiments if Tony wasn't interested. Presuming that Helen Cho survived the Snap, she would have been even more qualified to experiment on Vision. They could have even gotten a S.H.I.E.L.D. scientist, like Jemma Simmons, to do it, since the organization has more of a connection, regardless of its shakey history, to the Avengers than S.W.O.R.D.
Furthermore, the security footage was from nine days ago, meaning that S.W.O.R.D. experimented on Vision's body recently. Vision died more than five years ago, before the Snap, and if the Avengers thought it prudent to experiment on their deceased colleague's body, it seems strange that they would wait five years to do it, raising more questions about this dissection.
While it's unclear when or why Vision came into S.W.O.R.D.'s custody, it's clear this was under Hayward's control as the director of the organization. Hayward only took control of S.W.O.R.D. after Maria's death two years ago, and it's established he has a more cynical outlook on the world than Maria, especially after the Snap. This is also emphasized by Monica's reaction to the footage. She was surprised that SWORD had Vision's body and surprised by what they were doing with it. This implies that the S.W.O.R.D. Monica knew wouldn't have taken the body of an Avenger and cut it into pieces.
Hayward was casual about this, but the only reason he'd have his people dissecting a synthezoid would be to study or replicate the technology in it. This, in addition to Hayward's dismissal of Wanda and his willingness to shoot her against Monica's advice, casts a sinister shadow on Hayward and his iteration of S.W.O.R.D.
