Langsdorff after the scuttling of Admiral Graf Spee

Why did Hans Langsdorff take his own life after scuttling Admiral Graf Spee?

Possibly from a mixture of feared reprisals, guilt, and reluctance to play a further part in a war whose direction he could already see.

Langsdorff's decision is not reduced to a single cause. Fear of reprisals may have mattered, along with guilt and his possible understanding of the war's direction. The answer is explicitly speculative rather than a documented psychological diagnosis. It keeps personal responsibility, institutional pressure, and the wider conflict in view together.
