Thomas Andrews was considered a hero by those present.
On 14 April at 11:40 PM, the Titanic struck an iceberg on the ship's starboard side. Andrews had been in his stateroom, planning changes he wanted to make to the ship, and barely noticed the collision. Captain Edward J. Smith had Andrews summoned to help examine the damage. Andrews and Captain Smith discussed the damage to the ship shortly after midnight, after Andrews had toured the damaged section of the ship and received several reports of the vessel's damage. Andrews determined that the first five of the ship's watertight compartments were rapidly flooding. Andrews knew that if more than four of the ship's compartments flooded, it would inevitably sink. He relayed this information to Captain Smith, stating that it was a 'mathematical certainty', and adding that in his opinion, the vessel had only about an hour before it completely sank. He also informed Smith of the severe shortage of lifeboats on board the ship.
As the evacuation of the Titanic began, Andrews tirelessly searched staterooms telling the passengers to put on lifebelts and go up on deck.[3] Several survivors testify to have met or spotted Andrews several times. Fully aware of the short time the ship had left and of the lack of lifeboat space for all passengers and crew, he continued to urge reluctant people into the lifeboats in the hope of filling them with as many people as possible.
He later threw deck chairs into the water to assist people.
I do not think this guy went to hell, although hell is for heroes.
