I will put the Chinese version at the end of the article.

我将在文章末尾放上中文版。

Let me explain first that everything I'm going to say is Snape's shortcomings. You are welcome to discuss it, but impolite readers are not welcome.

I admit his courage and admire his later contributions and sacrifices to defeat Voldemort, but this doesn't affect my dislike of him.Because I can't stand the kind of malice that emanates from him all the time.

Snape has played many roles in his life, such as double-faced spy, death eater, and even hero. All these roles can be said to be very successful, but only one role is incomparably unsuccessful, and this role is the teacher. I deeply believe that as long as anyone who has read Harry Potter will not think Snape is a good teacher. His theoretical knowledge may be excellent and his teaching methods are good, but I don't approve of his teacher's morality.

He favors Slytherin students and makes things difficult for Harry. But today, I want to talk about another person, Neville Longbottom.

If Snape's malice towards Harry is due to his enmity with James Potter in his schooldays, how can he explain his malice towards Neville, who has nothing to do with himself?

Neville was ridiculed by Snape because of his lack of talent in potions class. Snape also experimented with Neville's pet Toad, even though he didn't care about its life or death. Hermione couldn't help but save Toad's life, and Snape in turn deducted Gryffindor's points. This toad is a gift from Neville's family, which means a lot to him. If this toad really dies, what a blow will it be to a teenager?

It was in this environment that Neville spent his five-year potions class (six years if you count the year Snape taught defense against the dark arts), and even Boggart became Snape's image in front of Neville. It is conceivable how much pain Snape caused him.

What is Snape's reason for doing this to Neville? Rowling said in the interview that Snape thought that if Voldemort had identified Neville as the enemy, Lily would not have died.

Does he love Lily? Yes. Is what Snape has done for her touching? Yes. I couldn't help crying when I read the scene of Snape calling out the Patronum and crying with Lily's body in his arms. But even so, there is a fact that can't be changed anyway, that is, Snape's love for Lily is very distorted, selfish and possessive.

All Snape cared about from beginning to end was Lily's life, but nothing else. As long as Lily can live, everything else doesn't matter, even if the price to be paid is Lily's husband and children, and even if the price to be paid may be the blood of other innocent people, it doesn't matter to him.

But he doesn't understand at all that the reason for Lily's break with him is not the simple "mudblood" but the difference of moral values.

This is the real pity of Snape. He really loves Lily, but he has never really known her and never thought about changing anything for her. By the time he really realized this, Lily had already turned into a dead bone in the grave. What a sad fact this is.

However, I admit that Snape is indeed a brave man, and he is a real hero.

我先解释一下，我要说的都是斯内普的缺点。欢迎大家讨论，不欢迎没有礼貌的读者。

我承认他的勇气，也钦佩他后来为打败伏地魔所做的贡献和牺牲，但这并不影响我对他的厌恶。因为我受不了他一直散发出来的那种恶意。

斯内普一生演过很多角色，双面间谍，食死徒，甚至英雄。这些角色都可以说是非常成功的，但是只有一个角色是无比不成功的，这个角色就是老师。我深深相信，只要读过《哈利·波特》的人都不会认为斯内普是个好老师。他的理论知识可能很优秀，教学方法也不错，但他的师德我不认可。

他偏袒斯莱特林的学生，给哈利制造困难。但是今天，我想谈谈另一个人，纳威·隆巴顿。

如果斯内普对哈利的恶意是因为学生时代对詹姆斯·波特的敌意，那他怎么解释他对与自己无关的纳威的恶意呢？

纳威因为在魔药课上缺乏天赋而被斯内普嘲笑。斯内普还拿纳威的宠物蟾蜍做实验，尽管他根本不在乎它的死活。赫敏忍不住救了蛤蟆一命，斯内普反过来扣了格兰芬多的分。这只蟾蜍是纳威家的礼物，对他来说意义重大。如果这只癞蛤蟆真的死了，对一个少年会是怎样的打击？

纳威就是在这样的环境中度过了他的五年魔药课(如果算上斯内普教黑魔法防御术的那一年，就是六年)，就连博格特也成了斯内普在纳威面前的形象。可想而知斯内普给他带来了多大的痛苦。

斯内普这样对纳威的理由是什么？罗琳在采访中说，斯内普认为如果伏地魔认定纳威是敌人，莉莉就不会死。

他爱莉莉吗？是的。斯内普对她的所作所为是否感人？是的。当我读到斯内普呼唤守护神，抱着莉莉的尸体哭泣的那一幕时，我忍不住哭了。但即便如此，有一个事实是无论如何也改变不了的，那就是斯内普对莉莉的爱是非常扭曲、自私和占有欲的。

斯内普自始至终关心的都是莉莉的生命，除此之外什么都不关心。只要莉莉能活下去，其他一切都无所谓，哪怕要付出的代价是莉莉的丈夫和孩子，哪怕要付出的代价可能是其他无辜者的鲜血，对他来说都无所谓。

但他完全不明白，莉莉和他决裂的原因不是简单的“泥巴种”，而是道德观的不同。

这才是斯内普真正的遗憾。他真的很爱莉莉，但是他从来没有真正了解过她，也没有想过为她改变什么。等他真正意识到这一点的时候，莉莉已经变成了坟墓里的一具尸骨。这是多么可悲的事实。

不过，我承认斯内普确实是一个勇敢的人，他是一个真正的英雄。
