Hubris is the word.

The CEO Stockton Rush, just off the top of my head:

• Fired his own director of marine operations for formally reporting “numerous issues that posed serious safety concerns". These included that the viewport was only rated to 1,300 meters, the carbon fiber hull had flaws which gave it the potential to fail, and that the hull integrity monitoring systems installed in response “might only provide ‘milliseconds’ of warning before a catastrophic implosion”.
• Refused to submit to an industry certification process for the sub, despite being warned in an open letter with dozens of signatories that failing to do so risked “negative outcomes (from minor to catastrophic)”.
• Denounced the laws regulating submarine tourism as having “needlessly prioritized passenger safety over commercial innovation”.
