The definition of 'Pentiment' is an artwork which has been revealed underneath another artwork, covering it. It's also a description of the thrust of the game - Tassing itself, and its' traditions, are a cover-up of the Ancient Roman faith, even down to the Rathaus literally sitting on top of the Roman ruins.
It's also a neat way of looking at the relation between Magdalene and Andreas - the one artist overshadowing the other.
When Andreas and Magdalene speak to people in Tassing, their dialogue bubbles appear with spelling mistakes, which get crossed out and corrected. This connects to the theme of the game and its' title as stated above, but it's also a representation of verbal tics and accents.
It may also represent levels of education - notably, the monks, nuns and gentry tend not to have so many spelling mistakes themselves.
Claus, Magdalene, and other characters with printing press speech tend not to have spelling mistakes at all - like the press, they tend to be able to consider their words ahead of time.
The inability to get Piero and Martin executed at all would be a case of Archdeacon Estler not willing to take Gernot's charges on Piero at face value despite standing by the accusation of him as the murder suspect in court procedures. While any four suspects in Act I can be condemned based on the amount of evidence presented for each of them, the court would have been careful enough to reevaluate the accusation even willing to execute one with a better alibi if Andreas tries to persuade the court to pick one of two suspects. In addition, the Abbott already had the town doctor and Brother Florian inspecting the corpse, Archdeacon would have been notified of their findings that would further prove Brother Piero and Martin's innocence.
In chapter II, once the death of Otto is discovered, Andreas asks his assistant Caspar to check his body for a note from the Thread-Puller, but Caspar doesn't find one. We know from earlier that Otto is one of the few remaining illiterate people in the town, a fact which would make the Thread-Puller's MO of using notes to bring the intended victim and potential killers into the same location useless. The Thread-Puller likely told Otto to go to the Radhaus at the appointed time directly. Considering Otto trusted Father Thomas implicitly, he'd have done so willingly.

Thanks to both the tight time limits and the lack of definitive evidence, it's entirely possible that you have ended up accusing the wrong person, condemning an innocent to death and letting a killer go free.
In the family tree you see in the game's ending, the camera briefly pauses on an image of Vacslav - Smokey's Romani friend - and Ursula being burnt at the stake. If you spoke to them as Andreas and/or Magadelene, this comes as no surprise: Vacslav was a heretical theorist who subscribed to the theory that Jesus the Son was a distinct being from God the Father, rather than a unified being; and Ursula still harboured aggressive thoughts about the ruling classes based on her traumatic memories of being sick and starving as a child, and watching her father Peter die in the revolt. It follows that Tassing's Lord would punish both for their perceived sins.
This, like most other in-game consequences, depends on the player's choices. At least one of them may be spared from the fire, depending on the conversations had with Ursula and Vaclav. And if Prior Ferenc is still alive the ending instead shows both Vacslav and Ursula on their knees praying, being spared for their heresy in exchange for performing penance.
Considering that the game was set in Great Reformation, it is only a matter of time before Tassing would be consumed by the 30 Years War and the sectarian tensions that led up to the conflict. In fact, Magdalene can bring up Protestant rebellions to one of the Poor Clare's nuns in order for her to remain there. Since the Tassing's regional lord is a devout Catholic, many of Tassing's Protestants would have faced persecution.
As Henry VIII would institute the Church of England and crack down on Catholic monasteries in 1534—9 years after Act II—Aedoc's fate would be dire unless he died or left England before that time.
