Osama bin Laden's death

Was the decision to assassinate bin Laden rather than bring him to trail a justified one?

I think the decision to assassinate bin Laden is a justified one. One reason why it is a justified one is because in the 1990s bin Laden's al-Qaeda assisted jihadis financially and sometimes militarily in Algeria, Egypt and Afghanistan. In 1992 or 1993 bin Laden sent an emissary, Qari el-Said, with $40,000 to Algeria to aid the Islamists and urge war rather than negotiation with the government. Their advice was heeded but the war that followed killed 150,000–200,000 Algerians and ended with Islamist surrender to the government. That means that bin Laden killed a lot of people with assistance from other terrorist, which resulted in massive destruction and deaths of thousands. Thus, I can conclude that the decision to assassinate bin Laden rather than bring him to trail a justified one because he do not deserve forgiveness after the deaths he caused.
