Not at all! Capybaras “Carpinchos” in Spanish, are a friend to all animals and people. In fact, it is very rare for one to attack a child or house pet. Much less dangerous than dogs and cats.
The Nordelta situation is rare - those are the carpincho’s habitats which in recent decades have been drained and turned into country clubs. But, the biggest river and wetland system in the region is having a historic low water level, so perhaps that’s why more and more carpinchos are coming down towards buenos aires. Another compounding effect is that the country clubs pushed larger predatory species, so there are more carpinchos on less swamp.
[EDIT: forgot to mention another issue is that these Country Clubs are notorious for ‘seeding’ their neighborhoods with deer and carpinchos when they’re selling units, to make things look more ‘nature-y’. So one biologist consulted by the local newspaper mentioned that since carpinchos are family groups, they can’t go where other groups already are, leading them to seek new territory.]
