Poisoned villains

Villains that died poisoned or in some cases, who were poisoned but survived. In some cases, just as many arsonists die of their own fires, poisoners can also die with their own poison, in the temptation to poison someone or commit suicide. A good example of this is the villain Clóvis, from O profeta, who tried to poison the villain Ruth too and who ended up taking it was him, since she changed the drinks as soon as she realized that he intended to kill her.
