"as evidence to prove this person sitting here killed the CEO, all the executives got scared and one even changed their physical appearance"

I don't see what the point of bringing this up, unless you are trying to present as evidence.

Monsters being afraid of lightbulbs being shone on their misdeeds isn't proof of anything other than the fact that they are afraid that their actions will get them the same body bag that their ~~victims~~ customers get.

They feel only the threat of immediate retaliatory killing and changing physical appearance were their best chance of preventing themselves from coming to harm, rather than getting people the medical treatment they need.

Honestly their best defence would have been to immediately say "oh thank God he's gone, we can finally start approving the much needed care we have always wanted to" and spend a week or two eating money until people are convinced they aren't soulless ghouls. Whether they believe it or not doesn't matter, they could have maxed out their PR but instead decided more money was the better option.

I've no sympathy at all.
