It's not a matter of pride. While the Chinese method does not involve mass killing, it still demands a pretty extraordinary level of political repression and vast material resources.
First, Israel would need to construct several massive, highly robust internment/education facilities each capable of accommodating and reconfiguring the brains of potentially tens of thousands of prisoners. They would then need to physically conquer and permanently occupy Gaza, to make it possible for them to surveil, identify, track, and arrest anybody found to be supporting Hamas or expressing sympathy for the organization or its ideals, which would probably be at least half the population, and then send them to these facilities to be 're-educated'. On top of this, Israel would also need to commit the necessary economic resources to provide the prisoners job opportunities after their sentences of generally 1-2 years, to ensure that they would not relapse into extremism after release. They would also need to justify all of this in the eyes of the international community, which would not necessarily be easier than justifying what they are currently doing, and may be harder given the invasive nature of the repression employed.
Israel is a small country, it simply lacks enough people and the capability to produce enough mass of the relevant products to make an effort like this work. Pride has nothing to do with it.
