I meant that there is always a tragic end to every experiment we have seen so far.

The main reason AC was founded in the first place was to create a Level 6 Esper. Other than that it serves as a semi-reliable measure to control the Kihara clan ('semi' because they are only there due to AC's position as the center of the world's scientific research).

not exactly, with body crystal they destroyed their body :D

and with Accel's brain they destroyed their own personality, the great difference is that the affects of body crystal can be healed but Accel ghost inside of you is worse than all the 103.000 grimoire together :D 

They did not create the Body Crystal to destroy their bodies but to increase their powers. The damage you're referring to is inflicted simply because Gensei (or anyone else who was involved in the manufacture of BC) hadn't put as much effort in the safety of his test subjects as on the effectiveness (in the context of increasing the test subjects Level).

Besides, Dark May involved replicating the power of Accelerator - the only Level 5 that can become a stable Level 6.

Finally, yes I understood halfway writing that I partly misread what you just quoted, it is still pretty much a miracle that Rikuo managed to heal from the side effects of BC. Most other characters that got involved with the experiments carried in the Dark Side of AC hardly ever recover that well (Kiyama's students, for example).
