It may be this reason that he knew that he would not have a good end after being caught, so he chose to kill himself. I think this matter is understandable. After all, he is a policeman, he knows the law very well, and he knows what he will face. He can't live anyway, and he can't escape. After all, the internet and everything are so developed now, no matter where he escapes, he is likely to be caught back, and he has no energy to run again. It is because he wants to wear these that he will choose to commit suicide. It's really pathetic.
Some people may think that it is really wrong for me to sympathize with a murderer, but we need to know the cause and effect of this matter. He is a policeman. He is a very good policeman. He has done good deeds twice in a short time. This shows that he is not a heinous person, on the contrary, he is a very honest and kind person. But because of a wrong relationship, I met the wrong person and ruined his life. I think it's really a pity that he should have a bright future, but it has become like this, and there is nothing left.
