kitty pride is a good person but she will kill to protect logan her teammates she considers family.. she may not like it but killing hulk who was such a big threat would have bn her most likely choice once ppl were getting seriously injured from sticking her hand into his brain and spine and solidifying enough to cause feed back and disrupt his brain's electrical impulses to even removing the organ itself..
she is a killer.. and has killed.
Xavier was able to shoot a massive planetary blast with the entire worlds fear and pain... he should not have any problem putting aside hulks rage when he is manipulating an entire planets psionic cries..
xavier was able to probe galactus mind and normal lvl defenses your telling me hulks rage gives him better protection then galactus.. now if galactus wanted to yes he could easily shunt out xavier which he did after their conversation.
nxt xavier has mind f@%^@ logan while in in his little rage fits and even outright turned him into a vegetable and baby in his onslaught storyline while making fun of his mental implants defenses, false memories and animal rage.. yet hulks rage is superior to psi blocks.. booby traps and primal rage being used as one? keep in mind that adamantium actually makes it even more difficult to mind scan and attack ppl.
