Though Tyson weighs every risk against its reward, never taking an unnecessary risk and having a backup plan for every backup plan, Tyson’s interpretation of which risks are worthwhile is a little …off and his confusingly big heart betrays him every time.
The risk of fugu verses its deliciousness would not be worth it to Tyson as he generally dislikes having to eat anyway. In that case, the risk exists for the sake of a risk rather than any tangible reward for Tyson.
The risk of burning up to bask in the warmth of the Moriarty Mirrors or The Colonel is a risk that Tyson will take every time without failure. Even in Tyson’s mind, it’s not a risk of burning up. He knows he will burn to make them happy, and Tyson is fine with that. He welcomes it with open arms.
Our dear Icarus will not flinch from his fate.
He trusts in mathematics completely, he trusts his ability as a mathematician to weigh the odds in his favour, and minimise the risks. To mitigate them. He plays it safe. However, Tyson knows that his emotions will always override that reasoning. He will do everything he can to reduce the level of risk, to ensure he can survive the repercussions, but Tyson is compelled to make those risks if it will benefit another. Those risks become worthwhile.
Tyson would claim that the biggest risks he has ever taken were joining the army to spite his father and trusting The Colonel. Those were risks he took blindly - without thinking through the consequences and without accepting the cost before he paid it, as he accepted them when he chose to join the Moriarty Mirrors - but Tyson will never regret taking those chances.
For all his incredible talent to survive, Tyson sees any damage to himself as far less important as the risk that someone else might be briefly inconvenienced by him not endangering himself; an exaggeration of the situation, perhaps, but truer than Tyson would ever care to admit.
He won’t risk a hand in a game of cards, because Tyson can card count flawlessly and has removed practically all risk. He knows the outcome already, and any loss of money is meaningless to him regardless.
It is unnecessary for him to risk getting hurt by someone he suspects could be untrustworthy, especially after everything The Colonel put him through. However, Tyson will view it as entirely necessary to throw himself in the line of fire to protect a complete stranger from harm or slander.
It’s not that Tyson never takes a risk.
Tyson has an incredibly risky job and shockingly little self-preservation, self-worth. Tyson will never take an unnecessary risk, because Tyson has the skills to justify why every risk that must be taken and to make those risks near inconsequential; by going out of his way to ensure their success and his survival.
He takes calculated risks. The risks where Tyson deems the reward worth the danger it presents. Risks where Tyson is either completely confident in his ability to succeed or where Tyson has accepted the price that must be paid and deemed it worthy, whether he succeeds or fails.
