It says that after their first meeting (which was only at a glance) Juliet was overcome by Romeo’s passion. This is ridiculous and they were foolish to even consider the thought of eloping at such a young age. My views I think are also one of the views Friar Lawrence had. When Romeo approached Friar Lawrence to perform the marital service Friar Lawrence rightly pointed out that he was also recently lovesick over Rosalind. I think the couple rushed ideas and did not think any thing through clearly. They were partly to blame for their unfortunate deaths.
I think killing Tybalt was the biggest mistake Romeo made as it led to him being banished and it meant he could not see Juliet again, without the risk of being caught. I don’t think though that you can blame Romeo for killing Tybalt as he was determined to fight Romeo and when he refused, Romeo’s friend Mercutio called Tybolt to fight. They fought and Romeo in tried to stop them but this ended up with Mercutio dying by the hands of Tybalt. “I was hurt under your arm”. Romeo then fought and killed Tybalt. When he finds out that Juliet is dead he says, “Then I defy you stars”, meaning he is not going to let Fate decide what happens to him anymore.
Here there is also a point of seeing Mercutio to be the one to blame. If Romeo did not want to fight Tybolt then really Mercutio should not have got involved and due to this Romeo looses his temper and fights Tybolt and has a result Tybolt dies and Romeo get banished.
One of the characters that I think are most blame is Friar Laurence even though his intentions were good but is continued to make risky decisions for Romeo and Juliet e.g. agreeing to marry them without their parents permission.
Hoping that Romeo would receive the letter from the Friar, he would return to Verona from Mantua and would be with Juliet when she wakes up. Juliet was very pleased to receive the potion from Friar Laurence
“Give me, give me! Oh tell me not of fear!”
Another character that there is to blame is the nurse for helping Juliet in the first place if she was not going to stick my Juliet when she needed her the most (when Romeo had got banished and Lord Capulet was telling Juliet to marry Paris). She should have helped her through it rather then turning her back and telling her to marry Paris to save her job.
The families in a sense were also to blame. I understand that the dispute had been carried on throughout the decades and it had almost become a tradition, but after realising the intensity of the feelings of their children, they should have at least if not forget the dispute completely just for the sake of their children put their childish disagreements to the side for a little while. They learnt in the end, but by then it was too late.
