You are conflating capitalism with corporations; they are not at all the same thing. The former is an economic system, whereas the latter is the legal creation of a fictional “person” for the express purpose of shielding private individuals from legal consequences.

Mind you, that is not always a bad thing. If someone decides to start a new business using a portion of their savings, it is arguably good to allow them to do so in such a way that if the business fails (and my understanding is that something like 90% of them do, so this is the overwhelmingly most likely outcome) then they lose only their investment and not their entire life savings or worse end up deeply in personal debt because otherwise we as a society would lose out on a lot of beneficial enterprises due to them being too risky. The problem comes in when this legal fiction acts as such a strong shield that it enables and encourages people to act in extremely harmful ways with virtual impunity because only the fictional person that is the corporation gets punished rather than the individuals who made the harmful decisions.
