In a healthy society, learning emotional control is part of growing up. If people in a society are constantly engaging in angry outbursts, it means they feel the need to engage in some kind of threat display, which in turn indicates they're living in fear. If you walk into an organization and discover all the bosses are constantly screaming at their obsequious underlings, who are in turn screaming at their underlings and so on down the line, it probably means everyone's afraid of losing their jobs, and it's a good idea to turn around and walk out the door, if that's an option. People who deliberately get angry (or sad) in order to get others to do what they want are engaging in emotional manipulation practices, which should be treated as a huge red flag. Such behavior is a common side effect of growing up with manipulative, unhinged and/or abusive parents, and it can be overcome, if the person wants to - but some people get addicted to their emotional highs and lows. Fundamentally, making good decisions under stress requires a calm rational mind not given to emotional breakdowns and outbursts, and people who don't have that capability should never be placed in positions of responsibility.
