Wasting water while performing wudhu

Q: From the following ibarat it is understood it is totally impermissible to leave the tap open during wudhu. E.g while doing masah of the head. Is this correct?

وفي الدر ويكره الإسراف فيه تحريما لو بماء النهر أو المملوك له أما الموقوف على من يتطهر به ومنه ماء المدارس فحرام اهـ. حاشية الطحطاوي على مراقي الفلاح شرح نور الإيضاح . ( قوله : فحرام ) لأن الزيادة غير مأذون بها لأنه إنما يوقف ويساق لمن يتوضأ الوضوء الشرعي ولم يقصد إباحتها لغير ذلك حلية ، وينبغي تقييده بما ليس بجار كالذي في صهريج أو حوض أو نحو إبريق ، أما الجاري كماء مدارس دمشق وجوامعها فهو من المباح كماء النهر كما أفاده الرحمتي . رد المحتار وَالْكَرَاهَةُ فِيمَا إِذَا كَانَ الْمَاءُ مَمْلُوكًا أَوْ مُبَاحًا، أَمَّا الْمَاءُ الْمَوْقُوفُ عَلَى مَنْ يَتَطَهَّرُ بِهِ - وَمِنْهُ مَاءُ الْمَدَارِسِ - فَإِنَّ الزِّيَادَةَ فِيهِ عَلَى الثَّلاَثِ حَرَامٌ عِنْدَ الْجَمِيعِ، لِكَوْنِهَا غَيْرَ مَأْذُونٍ بِهَا، لأَِنَّهُ إِنَّمَا يُوقَفُ وَيُسَاقُ لِمَنْ يَتَوَضَّأُ الْوُضُوءَ الشَّرْعِيَّ، وَلَمْ يَقْصِدْ إِبَاحَتَهَا لِغَيْرِ ذَلِكَ.

Tearing up one's step father's visa

Q: My mom married someone who my mom brought to uk. When time came for his visa to be renewed my mom had two choice one to give him permanent or just extend. My mom wanted to give him just extended because she did not like his behaviour as it changed as he was already married as well. According to my mother he threatened her and said if you don't give me permanent visa I will tell everyone you married me as it was kept a secret. Also he said when you go back you watch what happens something along the lines. Due to the threats and pressure she applied for permanent visa but was very unsatisfied so she asked me to help her to collect his letter and destroy it. Which I did and due to destroying the letter he was deported as he had overstayed. Am I sinful as I just helped my mother. Now my mother does not speak to him for obvious reasons, there is no contact so if I had said something in anger to him am I sinful?
