Destiny is rated T for Teen (Destiny)
If you look on the ESRB website, it has detailed descriptions for most of the games. It looks like the decided factor is probably the blood effects and vocal feedback when characters are shot.

"Characters are occasionally impaled on glowing swords, and aliens can be seen stabbing fallen figures during some battle sequences. Gun fights are highlighted by realistic gunfire sound effects, explosions, and screams of pain. Human and alien characters emit spurts of blood when injured; players are able to shoot dead enemies, causing more blood to splash out. Blood is sometimes depicted on the walls and ground."
From what I can remember, there isn't much/any blood or cries of pain in Destiny.
