Because evil grows
Common sense is to say that evil grows because good is omitted, in part this is true, as evil is the absence of good, but this absence can be due to aporia (lack of knowledge), due to bad education that forms unenlightened minds and due to end out of pure pride and power.
Power is a way of legitimizing both good and evil, this is only possible through violence, and generalized violence is war, so this is the clearest and most unequivocal form of evil, in it intolerance, contempt for what is different, the imposition of ideas and injustices is facilitated.
Thus, at different times in our history, it was through violence that empires and dictators imposed their wills and ideologies, not without the consent of a large part of the population, which is why we remember bad education, whether through propaganda campaigns or through schooling itself. impoverished and malformed, the two issues are linked.
Therefore, it is necessary to pay attention to management at all levels, from our homes, neighborhoods and condominiums to power structures, small illegitimate actions, education for empathy, coexistence, cleaning and even leisure must be observed and guided by managers and public bodies in order to preserve common space and public goods.
The zeal for honesty, transparency, respectful dialogue between opinions that are not necessarily opposite, but different even if in completely divergent directions should not be a reason for hatred and violence, dialogue is always possible.
Evil needs polarization, radicalization (in the bad sense, there is the good sense of going to the root of a problem), pure disagreement as a way to justify and propagate violence.
Just like the seeds of a good tree, weeds and poisonous plants also have roots, they grew in a healthy plantation and the fact that they must grow together can be a mistake because they can suffocate the good seeds, pests and diseases in plants.
Care must also be taken to cure these pests, in agriculture several pesticides have already been condemned, and even disease-resistant plants can be questioned, genetic mutation can cause greater harm than expected, there is a lot of ethical dialogue about this.
Therefore, three precautions must be considered: the ethical education of valuing what is good, the zeal so that error and evil do not spread and finally the correction methods must be careful not to cause even greater harm.
