Are all Jem'Hadar implicit killers at birth?

Question

In the Star Trek: Deep Space Nine episode "The Abandoned", the child Jem'Hadar is essentially programmed from birth to become a killer.

Are all the Jem'Hadar programmed this way, or do they evolve naturally into brutal killers?

Answer 1

The Jem'Hadar are genetically engineered to kill and die for the founders. Their violent tendencies are intentional and bred from birth.

In the episode "To the Death" we learn that the Jem'Hadar are little more than biological weapons, bred in artifical wombs known as "hatcheries", possessed of genetic memories controlled by the changelings and chemically addicted to Ketracel White, without which they become irrationally violent and ultimately die.

VIRAK'KARA: We don't sleep.

DAX: How about getting something to eat?

VIRAK'KARA: The white is the only thing we need.

DAX: Don't sleep, don't eat. What do you do for relaxation?

VIRAK'KARA: Relaxation would only make us weak.

DAX: You people are no fun at all. Glad I'm not a Jem'Hadar woman.

VIRAK'KARA: There are no Jem'Hadar women.

DAX: So what do you do? Lay eggs?

VIRAK'KARA: Jem'Hadar are bred in birthing chambers. We are able to fight within three days of our emergence.

DAX: Lucky you. So let me get this straight. No food, so sleep, no women. No wonder you're so angry. After thirty or forty years of that, I'd be angry too.

VIRAK'KARA: No Jem'Hadar has ever lived thirty years [...] Few Jem'Hadar live that long. If we reach twenty we are considered Honoured Elders.

In "The Abandoned", the foundling Jam'Hadar boy is instinctively violent, eventually identifying that

I now know that anyone who is not a Jem'Hadar is my enemy.

Answer 2

Well, according to Memory Alpha,

Jem'Hadar were engineered to be soldiers and ship crews, and nothing more. Their culture shunned all forms of relaxation and recreation, on the belief that such things made them weak

This would seem to indicate that all Jem'Hadar are programmed from birth to be killers.
