If companies were really treated like people, they'd be in jail right now - at least in the US. But they wouldn't come out reformed, just beaten and bruised, ready to commit more crimes.
The point of treating companies like people is so no one in those companies can be held accountable. The worst case for them that the intangible "coorporation" did something wrong and now it has to go away, so the entire board moves to a new company under a new name that owns the same properties and has the same practices. Only now they have practice obfuscating their crimes.
What ends lives and careers for people are just a minor inconvinience to coorporations.
