Suicide Bomber or Martyr

Are suicide bombers actually martyrs or are the extremists who blow themselves up defeating their purpose and hurting their cause? I'm sure you can already see where I'm going with this, but I did want to point out some of the important differences between people who are willing to die for a cause and those who are willing to kill (even themselves) for a cause.

• A martyr is an active and open member of a religion or cause that consumes his whole life and he is not willing to relinquish his faith nor give up his cause no matter what. 
• A suicide bomber might be coerced into action and tends to be more interested in the possible rewards or infamy that can come with the task.
• A martyr does not want to die and will do everything short of turning against the cause to stay alive to work for the cause another day. 
• A suicide bomber expects to die and may feel that death is the only way to have an impact in the world.
• A martyr maintains a loving nonviolent stance, praying for his enemies and forgiving his executioners. 
• A suicide bomber hates those who don't agree with his cause and would kill them rather than allowing them an opportunity to change.

If groups like ISIS think that creating Christian, Jewish, and moderate Muslim martyrs is going to advance their cause, they are miserably mistaken. God will not be mocked. Using religion as an excuse to hate and kill is the worst kind of blasphemy.
