Not entirely sure that's the reason. At some point it seems that he was brought back to life to just so he could do the same thing over again just to end up dead. Mainly a test subject who fights back and is denied death.
In 5.5, 6.5, 7.5 you follow two people that helped hank (the main character) in MC 5 however you seem them again in MC 9 and they have to work to bring Hank back to life. At the cost of one of them dieing to bring him back.
Also after the amount of people he killed and the ways he has died before it does make sense he would come back again anyways.
The most interesting Antagonists is the Auditor and the Clown. The Auditor only fights in MC8-10 At the end of MC 10 he absorbs all the bodies around him to repair his bodies structural integrity. However he was unaware that one of the dead was the clown.
When you see him absorb the clown his body acts eradically and explodes into a black smoke. It pointed out the moment the clowns body was moving the analysis was: OH GOD NO
here is the conversation he had with the clown before he exploded
A:WHAT?!?
C:HELLO AGAIN!!!
A: NO!
C: YES!
A: NO! NO! NO!
C: YES!!! YES!!! YES!!!
then explosion. It's some wild series.
My flame shines bright. Just make sure not to get burned by it.
