Eric [Responsibility] - "you killed her and the child your own grandchild"
Priestley encourages the audience to sympathise with Eric. Despite the Inspectors attempts to enlighten the Birling family that they are all jointly responsible, Eric's accusation of blame upon his mother is tantamount (equivalent) to Mrs Birling's blame of the 'father'
He places all the blame upon his mother with repetition of second person pronouns. Absolving himself from any blame

Erics subconscious attempts to distance himself from his actions by switching from first person to third person, referring himself as "a chap" rather than "i".
Eric's trivialisation of such violence of a possible rape, through the colloquial use of "a chap" being a possible attempt to euphemise his actions

Eric's emotional response to the news of Eva's death as Priestley demonstrates his innate rectitude (morality) though the stage directions, where the adverb "involuntarily" demonstrates the moral nature of Eric as he could not suppress his emotional reaction; it is involuntary.
