The Hopes of a crocodile dashed, then sprayed along the Pan-American Highway

In a lake adjacent to the Panama Canal, beneath the vertiginous bridge that carries tourists to the Miraflores Lock to view the great container ships on their way to the Pacific Ocean, on a mud bank, lay a crocodile. Named Ignatius, the crocodile was over ten feet in length, and was considered the alpha-male of his territory: a role he wore with grace and humility, and he was greatly respected by the other animals in the vicinity. Though a proud and successful creature, Ignatius was privately irked following his discovery of an old copy of National Geographic in which he read of the mighty Nile River in Africa. In this river (he read) crocodiles grow up to 20 feet long, weighing in at over 1000 kg, and are the most successful predators throughout history. Their varied diet includes birds, fish, various antelope species, monitor lizards, snakes, and other predators including lions, leopards, hyenas, wild dogs as well as other crocodiles. Feeling suddenly claustrophobic (and quite provincial) in his small lake, Ignatius resolved to travel (by foot) to this paradise, in which he would grow, learn, and dine like a king.
He waddled from the bank into the lush jungle which bordered his lake. Without hesitation, Ignatius pressed on, sure that he was making the right decision. After a difficult hour over treacherous terrain, Ignatius met a porcupine, travelling in the opposite direction. Though they had never previously met, the porcupine knew Ignatius by reputation.
‘Where are you going to, Ignatius? You are far from your swamp here.’
‘I make my way to the mighty River Nile, in Egypt, to begin a new life.’
‘Egypt?! Crocodile, you cannot walk to Egypt! Egypt is many miles away, across oceans and desert. You will die! Return to your territory Ignatius, where you belong, and are loved.’
Ignatius considered the words of advice that this concerned friend had spoken as the prickle of quills scratched the inside of his throat. Though uncomfortable to swallow, the mammal provided some sustenance for his journey, and no small amount of flavour. He continued on his way.
Ignatius’ next obstacle (and regrettably, his last) was the Pan-American Highway. Undeterred by the speeding motorcars (and quite unaccustomed to submitting to any creature) Ignatius continued his forward momentum. His head met with the front wheel of an agricultural vehicle, which sprayed his brains, blood and fragments of skull along the road. The driver of the truck was a poor, but enterprising farmer. With great difficulty, he lifted the carcass of the beast onto the back of his truck and took it back to his family.

Now complete both of the following questions:
1 a) Was Ignatius right to try to reach the Nile? The porcupine would say that it was a foolish ambition, the farmer would assert that he made delicious steaks. Who was right? Give reasons for your answer.
