How could more lives have been saved on the Titanic? Was there one person or thing to blame ... besides the iceberg?

Other than the iceberg, the ship's speed and the coal fire are to blame for the sinking of the Titanic.

Explanation:

Its been reported that the ship had actually been on fire days while sailing. There was a coal fire below deck for days that the crew was unable to put out. Clearly, that didn't stop the ship from sailing the sea. By the time a coal fire is noticed, it's probably been burning for days or weeks. The Titanic was not built for speed or racing yet it was at full speed when crossing the Atlantic Ocean, the excessive speed could have been caused by the firefighting on board. Some people believe that with the fire causing the ship so much speed that it crashed into the iceberg. With all this in mind, more lives could have been saved if the fire was put out but the crew isn't to blame for the fire. In general, a coal fire is extremely difficult to deal with under the best circumstances; the crew was doing their best to fight the fire best they could at the time.
