Harry might be shocked and full of regret. He had finally come to understand Snape's true nature in the original story. In the fanfiction, if Snape tries to kill himself, Harry could feel that he had not done enough to reach out to Snape or show him some form of forgiveness or acceptance, and he would likely be deeply troubled by it.
In such a fanfiction, one possible reason could be his feeling of extreme isolation. After his estrangement from his family, he might have felt completely alone in the wizarding world. He was always so focused on rules and order, and when things didn't go as he planned, especially in his career and family relationships, it could have pushed him to this dark place.
His family would likely be in shock at first. The Weasleys are a close - knit family, and even though Percy had his differences with them, they still care deeply for him. They might feel guilty for not reaching out more or for being too harsh on him during their arguments.
In 'amy tries to kill sonic fanfic', it might be that Amy has been tricked by an enemy. The enemy could have made her believe Sonic has done something really bad. So, out of a sense of justice or revenge, she tries to take Sonic's life. However, it's all a big ruse, and Sonic has to figure out how to make Amy see the truth before it's too late.
I don't know who created this particular fanfic. There are so many Sonic fans out there creating various fanfics, and it's hard to pinpoint the creator without more information.
The way the fanfiction portrays his relationships can also show despair. If his friends try to reach out but he shuts them off, it's like he's in a deep hole of despair where he doesn't believe anyone can help. And his actions, such as isolating himself in a dark place, could be symbolic of his state of depression.
One possible reason could be his overwhelming guilt. Snape had a complex past, being involved in the Death Eaters and then switching sides. He might have felt that he could never truly be redeemed, especially with all the lives lost during the wizarding war that he had some part in, whether directly or indirectly. This guilt could have driven him to such a desperate act.
He could also try to dodge her attacks while still trying to reason with her. Naruto has a strong sense of loyalty and friendship, so he would likely be very reluctant to fight back against Sakura. He might keep asking her why she's doing this and try to get through to her emotional side.
She may also be forced to defend herself. Given her powers, she could use her super - speed or super - strength to avoid Clark's attacks. And she would probably be hurt, not just physically but also emotionally, because Clark's actions would be a betrayal of their relationship.
