I agree with Cacheperl pretty much. Constantin is one of those slightly unstable personalities. Has very bad relationship with parents, he comments his mom is more the type to hire assassins and his father considers him worthless. He doesn't take his responsibilities or life seriously. He isn't really a bad person but he also doesn't care about consequences ... he just does what feels right.
You get that from the very start where he gets wasted the night before the trip, causes damage to the bar in a fight due to his big mouth, and captured. He comes off as childish, immature, and irresponsible.
When you land the island his whole attitude is a bit like a child who hasn't grown-up. He is like "this is MY island now" and he wants to the lady governor to take him through the dangerous side of town (adventurous). It is like life is a game.
He is nice, and wants to do right, based on his talks with De Sardet, but gets into conflict with his own nature. He also is terrified of dying based on that talk when he discovers he has the Malichor.
So I think his somewhat unstable personality gets pushed over the edge when he gets it and then made worse when he gets a taste of power and realizes he doesn't have to die.
Gaining that much power can be very intoxicating, and can easily overwhelm someone like a drug (this is common in real life - the saying that power corrupts). His mind gets twisted and he wants to make some sort of paradise (in his own twisted mind) for him and his cousin, who was the only one he felt truly understood him and was always there for him.
I can see traces of narcissim but to me the bigger issues was more that he never seemed to really grow-up and had a lot of self-esteem issues ... so gaining the power he did near the end it easily over-whelmed him as it made him feel like somebody.
