I’ll narrow it down to 2 options you can just pick which one you like better (obviously change the words around and make it sound better and have it in a complete sentence when answering bc i just rambled down some hope this helps)
Romeo
He was impulsive and reckless with his decisions
He was trying to rush his marriage with Juliet when he knew the future consequences
He knew their families were enemies but ignored that
He killed himself without checking if Juliet had a heartbeat (he said himself he saw how red her lips or cheeks still were)
OR
Friar Lawrence
He knew about the families deep grudge but still decided to help them get married
He’s the adult here so he should know better
He was the one who gave Juliet the sleeping potion (it was such a risky plan since everyone thought she was dead INCLUDING Romeo, he depended on his one and only messenger to get the word out to Romeo to explain the whole Juliet thing but the messenger never got to Romeo)
