Bhagwan Shri Krishna has called the three tendencies (lust, anger, and greed) the doors to hell.

While describing the people having such demonic tendencies, Bhagwan has said-

• ahankāraṁ balaṁ darpaṁ kāmaṁ krodhaṁ cha sanśhritāḥ
  mām ātma-para-deheṣhu pradviṣhanto ’bhyasūyakāḥ (16:18)

  Blinded by egotism, strength, arrogance, desire, and anger, the demonic abuse Me, who am present in their own body and in the bodies of others.

• tān ahaṁ dviṣhataḥ krūrān sansāreṣhu narādhamān
  kṣhipāmy ajasram aśhubhān āsurīṣhv eva yoniṣhu (16:19)

  These cruel and hateful persons, the vile and vicious of humankind, I constantly hurl into the wombs of those with similar demoniac natures in the cycle of rebirth in the material world.

• tri-vidhaṁ narakasyedaṁ dvāraṁ nāśhanam ātmanaḥ
  kāmaḥ krodhas tathā lobhas tasmād etat trayaṁ tyajet (16:21)

  There are three gates leading to the hell of self-destruction for the soul—lust, anger, and greed. Therefore, one should abandon all three.

• In spite of this, most of the people of the world are entangled with the ‘Tamsik’ tendencies due to the qualities of this age. In today’s world, even your own blood is ready to strangle you. Real brothers are ready to take each other’s lives. Whenever there is such immense darkness in the world, the Supreme Power is forced to descend on the earth. Many saints have already predicted this.
