Islam in itself is not terrorism. Any religion if practiced without respect and tolerance to other religions and faiths results in terrorism. But, Islam contains certain guidelines or preachings which encourage intolerance towards anyone who doesn't follow their religion. It is these preachings which radicalise people towards violence.

All the religions and religious customs evolve over time. However, Islam has not evolved much due to inherent violence embedded in the practices of it. Hence, if these Practices which leads to violence are eliminated and the preachings of love towards fellow muslims is applied to everyone including those following other religions, then Islam is as good as other religions.
