I felt mixed when I heard Ben Franklin died.
Could you elaborate on what you were feeling?
I felt happy and sad.
You shouldn't be happy with someone died, but it's okay to have mixed feelings about it. You should avoid celebrating someone's death that you admired.
I felt very happy when I heard he was dead. I was drinking and celebrating his death when it happened. Then sadness hit me like a tidal wave after I got home.
Having mixed emotions about a person's death is normal, but expressing happiness about a death is too crass.
