One Jihad such as suicide bombing destroys human life, the majority of the time innocent human life. What I think you fail to understand is that neglecting Jihad at one extreme is better than neglecting Jihad which leads to many peoples death at another extreme. Or if you can find how the other extremes neglegance of Jihad destorys innocent life, then maybe I will give your theory more than a deep sigh.
Until then I will refer to these words as my point of reference, and I hope you read them carefully:
“Do not put yourself to destruction with your own hands”.
وَأَنفِقُواْ فِي سَبِيلِ اللّهِ وَلاَ تُلْقُواْ بِأَيْدِيكُمْ إِلَى التَّهْلُكَةِ وَأَحْسِنُوَاْ إِنَّ اللّهَ يُحِبُّ الْمُحْسِنِينَ
Also, a Tradition of the Prophet Muhammad says,
“And if somebody commits suicide with anything in this world, he will be tortured with that very thing on the Day of Resurrection.”
Suicide bombing involves killing oneself as well as others.
