Was suicide a good way for revenge on his wife?

A Japanese personality is driven into a corner now. Her husband had committed suicide before. His brother charged the personality had an affair with the other actor and it drove him to suicide. The husband couldn’t have children and the wife wanted to become pregnant with the other man.

The husband left his suicide note and his brother went public with the note. The wife broke up with the actor after his suicide and now she goes out with other boyfriend now. 

His suicide note has drawn blame on her and the actor. 

I guess the husband wanted to revenge himself on his wife. 

I don’t agree with suicide. I consider he made them broke up by his suicide.

I’m apprehensive the people expect suicide is the good way to revenge themselves on someone.
