  In this paper, we investigate the Weak Cosmic Censorship Conjecture in nearly
extremal Kerr black hole by absorbing particles . In previous work, they ignore
the process of black hole absorbing particles. They assume the whole particle
can be absorbed and the overspinning occurs. However, it is questionable
whether the whole particle can be absorbed. Therefore, we will investigate it
in this paper. We consider the absorption process of a particle with finite
size. During this absorption process, the black hole's parameters will change.
This change will prevent the rest part of particle enter black hole. We show
the part entering black hole can not overspin a nearly extremal Kerr black
hole. Different from Sorce and Wald, we solve the overspinning problem for Kerr
black hole without radiation effect or self-force effect. Further, we use this
process to a general black hole. Under three assumptions, we show if Weak
Cosmic Censorship Conjecture is valid for an extremal black hole by absorbing a
particle, it will be valid for the corresponding nearly extremal black hole. In
many situation, the extremal black holes satisfy Weak Cosmic Censorship
Conjecture and the corresponding nearly extremal black holes don't satisfy it.
Therefore, if those black holes satisfy three assumptions, these violations may
be solved by absorption process.
