Final answer:
Friar Lawrence does express remorse and admits to his part in the tragedy of 'Romeo and Juliet', but it's debatable if he truly accepts full responsibility or sees himself more as a victim of unfortunate events.
Step-by-step explanation:
The question of whether Friar Lawrence accepts responsibility for his role in the tragedy of Romeo and Juliet is complex. Throughout Shakespeare's play, the Friar makes several impactful decisions, including marrying Romeo and Juliet in secret and devising the plan that ultimately leads to their deaths.
While he does express remorse and admit his part in the tragic events when he says 'miscarried by my fault, let my old life be sacrificed', it's debatable whether he fully accepts responsibility or primarily sees himself as a victim of circumstance.
