Romeo & Juliet's Suicide
Romeo states to Juliet,” Can I go forward when my heart is here? Turn back, dull earth, and find thy center out” (Act: 2 Scene: 1). This is the best evidence to find in the play. They are the reason they are dead even if they didn't mean too.
Song Love Love Love
When you know I can't love. (Monster and Men). This song was picked because it describes exactly what's going on even if they don't know it. They can't love each other because of the fact that their from different families that are in a feud. So they still tried witch cause each others deaths in the end of the story/play.
Another way, Tybalt is also to blame would be he hated Romeo and did anything to try to kill or get rid of Romeo. Like when Tybalt said,"This, by voice, should be a Montague. Fetch me my rapier (Blade), boy" He also said,"Thou, wretched boy, that didst consort him here, shalt with him hence (Romeo) This shall determine that (act 2 scene 5).. He was going to kill him for just being at the party and no other reason. Again he had no trouble if he were to kill him.
