Guillotine is traditional

As is burning at the stake, or tarring and feathering, which is fitting for a quack, blackhanding (merely dipping his hands in tar) is the milder version of that one

Crucifixion is a fitting end for a poison spreading jew, you can do it upside down to make it Peter's cross instead of that of Christ

Impaling is kinda gross, but it's also part of the appeal, very unpleasant as every move he makes just drives the end deeper into his guts

Throwing him off a series of heights that start at ground level and gradually increase in height is a possible alternative to hanging

There's also the gibbet, being forced to sit or stand while immobilized inside a hanging cage and exposed to the elements while you slowly starve

Stocks are similar, but a bit too low class for him

Iron maiden is similar, but on the ground and keeps them immobilized with spikes that stop just before penetrating the victim, such that any move they make draws blood, forcing them to stand perfectly still

There's also the strap, which would break his bones, abd eventually his neck, the breaking wheel can extend it, and if placed in water, you can add partial drowning to his sentence

Rockpiling is great for making him slowly feel the crush, and the ground below can be made deliberately uncomfortable to be crushed against, or combine with the rack for a very bad time

Boiling alive is a good one that the inquisition perfected into a science, knowing how long the victim could be plunged between a boiling cauldron and another one filled with ice water

What about a spectacle, like the drawing abd quartering, where each limb is tied to the reins of a horse and the four horses are sent off from him in different directions

Another way to get animals involved is to use rodents for torture, just a bucket and a blowtorch is all ot takes to get them going, the other option is to get a goat or cat to lick him over and over until his skin peels off completely

The bronze bull is a good Greek torture, where he's placed in a hollow bull statue that has no air, except through a tube inked to its mouth, as he sucks air through the tube, a fire is started below, and slowly the temperature inside the bull rises, he screams through the tube, and his screams come out as bellowing from the bull

The Romans did one better with the colluseum, a massive circus in which he'd be well armed and equipped, them made to fight laughably inferior foes without end until he finally succumbs, a humiliating end, but also a great show for the observers

Blood eagles would be well recognized by the norsemen among us, as would scaphism

Being mummified while alive is another horrible means of execution, practiced on the condemned who would redeem themselves in the afterlife by guarding the honored dead, they would be made to have the full experience of being put through a modified version of the preserving process that was specially designed to keep them fully alive and conscious while the process was being performed on them until it was completed

Here's some Chinese tortures:

Skinning alive is also good, you could do lingshi and kill with a thousand cuts.

Water dripping on the forehead is underrated, it slowly drives the victim insane, best with icy water that causes the brain to feel as though it's shrinking.

The Chinese version of implementation is sitting him over a bamboo shoot, and waiting for it to grow up into his ass until he dies.

The best punishment is to be given injections of his own poison, over and over, one for every needle that killed one of his millions of patients

He will be told that each is the same as what they had taken, but in reality they will all be saline solutions

The point being that he I put through intense psychological torment until the last dose he takes, which will be a very potent mixture of the real deal shots

That is, all the vaccines he ever endorsed, mixed into one, split into individual shots, all of which he will receive, if he has a bad reaction, great effort will be taken to restore him, all so that he can get all the way to the final shot

If he survives that, he's still going to be very sick, so we keep him alive as long as we can, and name sure he feels every bit of that sickness

We will also take every effort his friends in the elites had to make sure he's as sick as can be until he finally dies, the chem filled air, the fluoridated water, the poisoned gmo food, the constant exposure to 5g, and of course the unending stress of the psychological torment the elite put the masses through, everything

If you knew Faucis's history of hanging out out gay bath houses for "research" you would know that he loves getting fucked in the ass.
