The fact that Harry was selected for a tournament in which people have died in the past, while there are people of people who'd like to kill him or see him die in an "accident" is bound to make Dumbledore nervous. The Tournament is designed to ensure nobody dies by accident, not from deliberate assassination attempts..
Moreover, why does Harry Potter have to compete in the Triwizard Tournament?
Never in the history of the tournament had there been a fourth competitor. It's called "Triwizard" for a reason — the competition represents one student from each school competing. The reason the Goblet of Fire chose Harry's name wasn't because he was deemed "worthy" of the honor like the other three champions.
Secondly, how did Harry get into the Triwizard Tournament? According to the book, Barty Crouch Jr. under the disguise of Alastor 'Mad-Eye' Moody by the influence of Polyjuice Potion nominated Harry for the Tri-Wizard Tournament. Barty also used his magical see-through eye to banish obstacles from Harry's path in the Third Task (maze). He turned the Cup to a Portkey.
In this way, what would've happened if Harry didn't compete in the Triwizard Tournament?
If it hadn't happened, Voldemort would have had to use a different spell or find a different way to bring his body back. If that had happened, Harry wouldn't have been able to choose to live after being AK'd in The Forbidden Forrest in DH. TL;DR- Harry would have died at the end of the story.
Why was everyone mad at Harry in Goblet of Fire?
Ron was angry because he believed Harry had gone behind his back to put his name in the Goblet. He felt Harry should have told him and taken him along so he could have put his name in too. Ron was upset that it was always Harry in the spotlight, never him.
