# XIII: A Corrupter of Thought explained — The Brothers Karamazov

> Chapter companion for The Brothers Karamazov by Fyodor Dostoevsky.

## What happens

Fetyukovitch delivers a passionate defense speech, arguing that the charge of parricide is based on prejudice rather than evidence. He redefines fatherhood as a rational, duty-bound relationship, not a mystical bond, and contends that Fyodor Pavlovitch was an unworthy father who neglected and abused Dmitri. He appeals to the jury to show mercy, suggesting that acquittal would save and regenerate Dmitri's soul, while conviction would destroy him.

## Themes in this chapter

### Fathers and Sons

Fetyukovitch redefines fatherhood as a rational duty, challenging the mystical bond and arguing that an unworthy father forfeits the title.

### Justice and Injustice

## Key lines

> the father is not merely he who begets the child, but he who begets it and does his duty by it.

A true father is defined by fulfilling his responsibilities, not just by biological paternity.

_Fetyukovitch argues for a rational, duty-based definition of fatherhood._

> Better acquit ten guilty men than punish one innocent man!

It is preferable to let ten criminals go free than to wrongly convict a single innocent person.

_Classic legal principle invoked to urge acquittal due to lack of evidence._
