When Dante enters Hell, Minos asks him, "Did Beatrice give you a smile when she came across you in the street?"
Dante replies, "No."
Minos shouts, "You're foolish, you and she are in two different parallel worlds, your zealousness is useless!"
Then Minos turns to Rhadamanthus, "Put the repairing task to him."
What's the task? For people in Nephalem hacked the message channel between Hell and Heaven, residents in Hell need a more secure channel reporting to Zeus.
Dante is very confident about the job, has done it in a week.
While Rhadamanthus runs through the source code Dante has just compiled and tested, Aeacus shakes his head violently, "Why do you not check the variables? You shouldn't call a memory operation function with null pointer variables. Look here and there, so many 'free' routines you invoked didn't obey this law."
"Must check?" Dante says with contempt and looks to Rhadamanthus for a reply.
"Yes." Rhadamanthus replies without hesitation.
This drops Dante in a situation that he needs to check himself first. He returns to his computer and begins to google the libc specifications, but he stops, and appeals to Minos, "Boss, are they right?"
"Of course! Because it's too dangerous without check, are you intend on ruining the Hell?" as is the deciding vote from Minos.
