The Hunger Games:

In the end:

Prim > Dies:
The parachute with the supplies fell over Prim at first. The second time she opened it, there weren't supplies as she expected. Instead, a bomb exploded on her face.

TRAGIC

Katniss > Psycologically Traumatized:

After she saw her sister die, she had done everything in vane. She hardly speak. She married Peeta and not Gale. Katniss said she needed Peeta's joy instead of Gale's seriousness.

TRAGIC

Peeta > Mad:

In the end, he was never the same. He stayed crazy and mad. After the game of "real or not real". He married Katniss and had children, but they couldn't get over The Games. 

TRAGIC

Gale > Depressed:

He loved Katniss more than everything. He was sad she didn't married her. That's all they mention. They take Gale out of the book about 8 chapters before the triology ended.

TRAGIC

President Snow > Dies:
Katniss and him had swear not to lie at each other. When Katniss is about to kill him, hw whisper "But, Mrss Everdeen, I thought we had agreed not to lie" (read Coin's). So she did't kill Snow. People from the Capitol and the Districts left him tied and he laughed so hard, he drowned on his own blood.

TRAGIC

(AND STUPID)

Coin > Betrayed:
Read Snow's first two lines. Then Katniss pointed at Coin with the arrow and killed her (Coin wanted Hunger Games with children from the Capitol)

LOYAL

Finnick > Sacrified:

When the beasts were running after them, he noticed (when they tried to scape) that they were going to die, so he died helping Annie, Peeta and Katniss.
