Who said anything about "evil US capitalists"?
There can be no excuses for neglecting the safety regulations that resulted in so many deaths, be it the "evil US capitalists" or whosoever responsible for neglecting the safety standards.
Uh, you have provided no proof whatsoever that Carbide "neglected the safety regulations". It's been some years since I studied the Bhopal issue, but all the major US chemical companies are absolute fanatics for safety (I worked at one for 25 years), so I seriously doubt that if any safety regs were violated, it was as a result of company policy.
