Most murderers will feel regret after murder Because they did not control their emotions properly when they are in the conflict. It is similar to William Shakespeare’s script Romeo and Juliet, he created a tragedy between two lovers. In the play, Romeo’s refusal to change his impulsive behavior when he has conflicts with other people contributes to his downfall. To put it another way Romeo’s “think to do” cause he and Juliet died. Firstly, when he first time met Juliet, he should not fall in love with Juliet; Secondly, Juliet should not kill Tybalt; Thirdly his behavior after he herded about Juliet’s died let the fate be unfixable.
